EYE on NPI – Sensirion SEN66 Environmental Sensor Node

This week's EYE ON NPI features a new 'everything' sensor, the Sensirion SEN66 Environmental Sensor Node (https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x) . This is a highly-anticipated update to the SEN5x (https://www.digikey.com/en/videos/s/sensirion/eye-on-npi-sen54-environmental-sensor-node) goes hard on gas sensing, with VOC, NOx and CO2 sensors built in. You can even update to the SEN68 and get formaldehyde HCHO sensing! What we like about this series is the complete solution for all kinds of environmental sensing with a single cable. Sensirion is one of our fav sensor companies: from classics like the SHT45 (https://www.adafruit.com/product/5665) to the popular SGP30 (https://www.adafruit.com/product/3709) and the high quality SCD30 (https://www.adafruit.com/product/4867) we have made breakouts for many-a-sensor from this company. Lately they've started to do fully integrated products - like the SEN5x series (https://www.digikey.com/en/videos/s/sensirion/eye-on-npi-sen54-environmental-sensor-node) that we covered earlier on EYE ON NPI. The SEN54 series has particulate matter (PM1, PM2.5, PM4, PM10) dust sensing, plus temperature, humidity, volatile organic compounds (VOCs), with the SEN55 adding NOx. We saw this sensor often paired with an SCD30 (https://www.digikey.com/short/d1h3t1n4) or SCD4x (https://www.digikey.com/short/zmh2zjz3) to add CO2 sensing. Those folks will like the look of the SEN6x series as now we get CO2 sensing in all but the lowest-cost SEN60. One thing to note with CO2 sensing is that once a week it needs to 'self-calibrated' by letting it sense fresh outdoor air which will be ~400ppm. This isn't a bad idea for your health either. Another new sensor added in the upcoming SEN68 is formaldehyde, which integrates the SFA30 (https://www.digikey.com/short/2d5fb8rt). If you've used the SEN5x series, (https://www.digikey.com/en/videos/s/sensirion/eye-on-npi-sen54-environmental-sensor-node) you're probably familiar with their connection interface: a JST GH 6-pin cable is used to connect and provide power and I2C data connection. However, one thing to note is that the cable is the same but the pinout has changed. Power is now 3.3V instead of 5.0 and there's no UART interface, so the SEL pin is not available. For that reason, if you'd like to use the same cable, go for it - but the circuitry will need to change...for example we're revising our SEN5x breakout (https://www.digikey.com/short/h0jffnm2)! We like that, just as with the SEN5x series, the SEN6x (https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x) uses plain I2C to communicate. This makes it easy to integrate with any microcontroller or microcomputer, and the added CRC helps avoid accidental data corruption from EMI or loose cables. The interface is not just to each individual sensor - there's only one I2C address and command structure and once you initialize the sensor you can read all values at once for 'timestamped' consistency. The commands are easy to implement, but if you want a head-start, check out the Sensirion GitHub account (https://github.com/Sensirion?q=sen6&type=all&language=&sort=), they have code in C and Python for a 5-minute quick start. Excited to check this fancy new combo-sensor out?

This week's EYE ON NPI is for those who need easy-to-maintain battery power for quick field maintenance - it's Bulgin's Battery Holders for Diverse Applications (https://www.digikey.com/en/product-highlight/b/bulgin/battery-holders-for-diverse-applications) a variety of battery enclosures and fixtures that will give your customers easy access to replace batteries no matter what size and configuration! If your product is going to be portable, or if you want battery back-up for timekeeping/configuration/sleep-modes, then you're going to need primary or secondary battery cells built into the design. Secondary cells (https://www.digikey.com/en/products/filter/batteries-rechargeable-secondary/91) are fairly popular these days: those are rechargeable batteries like Li-Poly packs. These are lightweight and high energy-density, which is why you see them everywhere from EV cars (https://www.digikey.com/en/blog/safety-first-approach-to-ev-and-battery-storage) to your Bluetooth earbuds. But they are not very user-friendly to replace, and if damaged can cause fires. They're also more challenging to ship by air due to restrictions on declarations and packaging of bare and with-equipment lithium cells. (https://www.ups.com/us/en/support/shipping-support/shipping-special-care-regulated-items/hazardous-materials-guide/how-to-ship-batteries) and for some field-use devices that may be used for long periods without being near a power outlet, being able to carry extra cells, for quick replacement, is a boon. For those reasons, there's still lots of products that run on your standard-issue primary batteries (https://digikey.com/en/products/filter/batteries-non-rechargeable-primary/90) a.k.a. 1.5V AAA, AA, C, D and 9V batteries. Of course, these days lots of people also use rechargeable NiMH in the same package: they are lower voltage, only 1.3V instead of 1.5V nominal, and have about 30% less energy but can be recharged safely/externally very easily. You can buy them at any corner store anywhere in the world for a few dollars and they have low self-discharge rates so they can be stored for many years. If you decide to go with standard-size batteries, you'll also need a way to hold them securely inside an enclosure. We like the look of these Bulgin battery holders (https://www.digikey.com/en/product-highlight/b/bulgin/battery-holders-for-diverse-applications) particularly the ones that mount to an enclosure wall and allow replacement without requiring a battery door that is custom molded. There's even options for IP67 hand-removable/replaceable covers for excellent waterproof-ness even in harsh environments while not sacrificing user-friendliness. On the inside of the enclosure you have solder lugs for easy attachment to your PCB by solder or spade connects. For many of the battery holders, a simple round drilled or punched hole is all that is needed. For your next battery-powered designs, take a look at Bulgin battery holders (https://www.digikey.com/en/product-highlight/b/bulgin/battery-holders-for-diverse-applications) - DigiKey has dozens of options in stock for immediate shipment. Order today and you'll get any of the Bulgin varieties shipped immediately so you can power your prototype by tomorrow afternoon!

Today on the Clean Power Hour, Tim Montague delves into the critical yet often overlooked aspect of electrification: EV charging infrastructure for multifamily housing. Tim welcomes Aubrey Gunnels, CEO and co-founder of 3V Infrastructure, a company that's tackling the significant gap in EV charging accessibility for the 31% of Americans living in multifamily buildings.Aubrey explains how 3V's business model works – they provide all capital expenditure and operational costs while installing Level 2 chargers at multifamily properties at zero cost to property owners. The company generates revenue by charging drivers a premium on electricity rates, creating a sustainable business model that doesn't rely heavily on government subsidies. This approach addresses a crucial market need, as currently, only about 5% of multifamily buildings have EV chargers despite 80% of charging happening at home.The conversation explores how 3V uses data-driven approaches to determine the optimal number of chargers for each property, considering factors like local EV registration data, building demographics, and anticipated growth patterns. Aubrey shares insights about how property managers see EV charging as an increasingly important amenity that affects NOI (Net Operating Income) and resident retention.Tim and Aubrey discuss the challenges of EV infrastructure development in the US compared to Europe, the importance of charger reliability, and how private investment in charging infrastructure remains critical regardless of policy shifts. They also touch on the broader EV market trends, battery price decreases, and how the automotive sector's global competitiveness continues to drive EV development despite political changes.This episode provides valuable insights for real estate owners, property managers, clean energy professionals, and anyone interested in the future of transportation electrification.

What if it were actually possible to power your EV from the sun collected on it's surface? Or what if you were not constrained by only one battery chemistry type but could mix chemistries? Want to charge 400 volts with a 3V unit? For 150 years, electrical engineers have relied on magnetic induction for power conversion, using coils and magnetic structures to transfer energy. These constraints result in energy waste, size restrictions, and chemistry challenges, preventing seamless transfer between low and high voltages. But what if you could control, manipulate, and augment the near-field reactive space by shaping it to do whatever you need? If you wrapped that kind of power up in a single element, it could deliver a potent “omni-converter” that could do things literally impossible by other technologies.Udi Daon, CEO of Daanaa Resolution Inc., is on a mission to eliminate power conversion inefficiencies, and redefining what's possible in energy efficiency. This serial entrepreneur quickly identified Daanaa's groundbreaking technology to revolutionize power conversion as soon as he saw it, which is why he was the fist investor and soon took the reins as CEO. Under his leadership, the company has developed a device that breaks free from magnetic reliance, instead using the entire electromagnetic spectrum, manipulating near-field reactive electromagnetic space to achieve ultra-efficient conversion. This technology can transform very low voltage into high voltage (and vice versa) in a single step with over 95% efficiency, opening up new possibilities for electric vehicles, solar panels, and data centers…and all in a package the size of your car's key fob!Tune-in as I tease out:How Daanaa's technology enables efficient power transfer without relying on traditional magnetic induction methods.The practical benefits of converting ultra-low voltage from solar cells into usable energy for EVs.How Daanaa's “omnipotency” boosts energy output from uneven surfaces with single-stage hyperconversion and bidirectional power.Udi Daon's unique approach to scaling deep-tech solutions and aligning teams for success.When I first met Udi (at Intersolar N. America a little over a year ago!) I was as skeptical as the next person when he told me what his pocket-sized device could achieve. And Udi says that this disbelief has been the hallmark (and primary hurdle) preventing their technology from scaling. But I, for one, think they're on the cusp of something truly remarkable. And you get to say “I heard it first, on SunCast!” ;-) Oh yeah, he's also got a Lot to share about startup culture, lessons learned, etc from dozens of companies he's founded or funded.You will definitely get your money's worth with this one!If you want to connect with today's guest, you'll find links to his contact info in the show notes on the blog at https://mysuncast.com/suncast-episodes/.Our Platinum Presenting Sponsor for SunCast is CPS America!SunCast is proudly supported by Trina Solar.You can learn more about all the sponsors who help make this show free for you at www.mysuncast.com/sponsors.Remember, you can always find resources, learn more about today's guest and explore recommendations, book links, and more than 730 other founder stories and startup advice at

L'épisodeQuel est le véritable problème de notre alimentation "moderne" ? Est-ce le sucre, le gras, ou bien quelque chose d'autre? L'épisode se concentre sur l'importance de repenser notre approche de l'alimentation. Au lieu de se concentrer uniquement sur les nutriments, il est essentiel de considérer la qualité de l'aliment en soi. Les invités discutent de la nécessité de réduire la consommation de produits ultra-transformés, qui sont souvent responsables de maladies chroniques, et de favoriser une alimentation plus naturelle et moins transformée. Parmi les points discutés il y a l'importance de l'éducation alimentaire dès le plus jeune âge et des solutions comme l'intégration de diététicien.ne.s scolaires et la taxation des produits ultra-transformés pour encourager des choix alimentaires plus sains et durables.Les invité.e.sL'invité principal de cet épisode est Anthony Fardet, un chercheur en alimentation préventive, durable et holistique.

EYE ON NPI - Nexperia NID5100 Ideal Diodes

This week's EYE ON NPI is the ideal component for your next power supply design, it's Nexperia's NID5100 Ideal Diodes (https://www.digikey.com/en/product-highlight/n/nexperia/nid5100-ideal-diodes) a simple design improvement to Schottky diodes or simple P-FET polarity protection. This small and low-cost component from Nexperia is their first 'ideal diode', and can be used in many low voltage power supply setups to reduce power loss and get you more product life from your battery Diodes, who doesn't love them? (https://en.wikipedia.org/wiki/Diode) You put some P-doped Silicon next to N-doped Silicon (https://en.wikipedia.org/wiki/P%E2%80%93n_junction) and before you know it, you have accidentally semiconductored! Make them big enough and you can even solve global warming (https://en.wikipedia.org/wiki/Photovoltaics) We use diodes all the time, and they're particularly useful for power supplies since they make sure current only goes one way. We often use them in front of a DC jack, between the power input and the circuitry: this keep the voltage polarity positive with respect to ground, since most modern microelectronic components want between 3-24VDC. Or, as an OR: either battery or USB power are hot-swapped so that whichever gives the highest voltage will run the downstream electronics - see our Trinket M0 schematic for a simple example (https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/downloads) When we first started electronics we'd use the classic 1N4001 (https://www.digikey.com/short/d8jn3f9v) - this low cost diode can handle high currents and about 1A continuous, with about 1-2V forward drop. When we did +12V power to an LM7805 (https://www.digikey.com/short/7vv3zc1d) this was fine, we have 5V to burn. Sometimes if we were feeling fancy we'd use a Schottky diode like the 1N5817 (https://www.digikey.com/short/8fntvnrv) which has about 0.7V drop, these are often used for boost or buck converters where you don't want to lose efficiency in your free-wheeling diode switch. But when using a 3.7V nominal voltage lipoly battery into a 3.3V regulator, we have to dial it down - even 0.7V is too high - so we'd often reach for a lower-drop Schottky like the Nexperia PMEG2010 (https://www.digikey.com/en/products/detail/nexperia-usa-inc/PMEG2010ER-115/2119861). We still use this part a lot, but we could do better with an Ideal Diode like the NID5100! (https://www.digikey.com/short/4td40hmh) Ideal diodes are as close as possible to the platonic ideal (https://en.wikipedia.org/wiki/Theory_of_forms#Ideal_state) of a diode as possible: Forward conduction only, with zero reverse conduction, and minimal voltage drop. Sometimes folks try to mimic this with a reversed P-FET and yes this will give minimal forward voltage drop for polarity protection (http://www.youtube.com/watch?v=IrB-FPcv1Dc), but it has 'infinite' reverse leakage instead of close-to-zero. The NID5100 is more complex, with additional circuitry for driving the P-FET. It can be used either as a polarity protection for a DC or battery input where there's risk of the voltage being inverted, or as an OR-ing voltage select. Compared to a Schottky, it can handle 1.5A continuous - most basic Schottky's are 1A - and with a forward voltage drop of only 50mV at 0.1A. The package size and price is also very comparable to a SOT323 diode, in an easy-to-place TSSOP6 and under 10 cents in reel quantity. We also like the extra pins like an Enable, so it can also act as an on/off switch, and a Status pin that lets you know when the diode is conducting: this can be used to detect which power supply is active in an OR setup. Does the Nexperia NID5100 (https://www.digikey.com/short/4td40hmh) sound like the ideal solution to reduce heat and power loss in your next product? Yes! And it's in stock right now at DigiKey for immediate shipment. Order today and you'll receive your components faster than a diode switching time, for integration into your BOM by tomorrow afternoon.

This week's EYE ON NPI is having Too Much Fun - it's the ams OSRAM TMF8806 Single-Zone direct Time of Flight sensor (https://www.digikey.com/en/product-highlight/a/ams/tmf8806-single-zone-tof) the latest in ams' series of ToF sensors. This sensor may seem like "YAToF" but there's a few things that caught our eye. One is the excellent pricing, about $2 in quantity. Another is the simplicity of function: unlike many ToF sensors, there isn't a massive firmware stack required to load on each boot. Instead, the default firmware is in ROM for a lightweight interface. We've stocked ToF sensors (https://www.adafruit.com/search?q=tof) for quite a while - mostly the ST VL series. These sensors have developed quite a bit over the years, starting with the 100mm-range VL6180 (https://www.adafruit.com/product/3316) and continuing onto multi-grid devices that we've covered on previous EYE ON NPI's (https://www.youtube.com/watch?v=3PocFz427NE). The way these work is by blasting laser pulses out of a VCSEL (https://en.wikipedia.org/wiki/Vertical-cavity_surface-emitting_laser) which then bounces off of the target and the 'time of flight' is measured in the pF range to give accuracy and range. Easy to describe, but non-trivial to implement...the light doesn't bounce off perfectly, and a lot of individualy measurements need to be taken and then averaged - this is called the histogram. The histogram data is filtered in software to toss outliers and double-bounces, to get the 'true' calibrated distance. And it has to do this dozens of times a second. The complexity of the algorithm is what gives each product its accuracy, precision, repeatability and range - so its no surprise that its running on an in-package microcontroller. However, as the sensors have gotten more advanced, the firmware process has also gotten complex: for many ToF sensors you have to 'load' the firmware algorithm on boot (https://github.com/STMicroelectronics/stm32-vl53l5cx/blob/main/modules/vl53l5cx_buffers.h#L33) and even if you don't, its a non-trivial port to other platform. That's what caught our eye for the ams OSRAM TMF8806 (https://www.digikey.com/short/f9v8w20d), the description specifies "No FW download is required to operate this device, saving host MCU memory space, reducing startup time, and saving overall system power by enabling customers to quickly start the device and make measurements in a few milliseconds". The interface is trivial, they even provide the I2C commands required to boot, load firmware, and perform a reading, its about a dozen commands. For hardware, it's also a nice and simple integration - with a small OLGA package, I2C communication, and 1.8V or 3.3V logic level. One thing to watch for, the sensor comes with 3 'modes' - short, medium and long range. Minimum range for all of these is 10mm, the max is 200, 2500 or 5000mm. And,while the sensor can do 5000mm, it requires pretty specific calibration and lighting. The default range is 2500 and we recommend sticking to that if you can because then you get the benefit of built-in configuration and calibration for speed/simplicity. To get started fast, ams OSRAM supplies multiple drivers for Arduino or other C microcontrollers (https://github.com/ams-OSRAM/tmf8806_driver_arduino), generic Python (https://github.com/ams-OSRAM/tmf8806_driver_python) and Linux kernel (https://github.com/ams-OSRAM/tmf8806_driver_linux). You can also grab an eval board in 'shield' format that has a microcontroller for plug-and play usage (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TMF8806-EVM-EB-SHIELD/24768739) Add low power, super fast ToF sensing to your next design with the ams OSRAM TMF8806 Single-Zone direct Time of Flight sensor (https://www.digikey.com/short/f9v8w20d), in stock for immediate shipment from DigiKey!

Back in the old days, before USB, we had to use RS-232 to communicate with computers. One of our first designs was the ATmex (https://www.ladyada.net/techproj/Atmex/index.html), a microcontroller board with a built in bootloader! We used the MAX232 (https://www.digikey.com/en/products/detail/texas-instruments/MAX232DR/555684) to convert 5V serial to +-10V RS-232. These days, with USB-Serial converter chips like the FT232 or CP2102, you'll still see remnants of that past, such as DTR and RTS pins.

This week's EYE ON NPI is catchy like an 80's pop song (https://www.youtube.com/watch?v=LPn0KFlbqX8), it's ams OSRAM's TCS3530 True Color Sensor (https://www.digikey.com/en/product-highlight/a/ams/tcs3530-true-color-sensor) It is a new light sensor from ams OSRAM that is pre-calibrated for CIE XYZ color temperature sensing output, without a lot of gnarly math! We're huge fans of ams's light sensors, one of our first sensor breakouts was the TSL2561, (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TSL2561T/3095179) a wide-input-range light sensor with an I2C interface. We followed that up with a breakout for the TCS34725 which can detect separate red, green, blue and clear channels. With a little math, color reflected off of objects can be calculated into RGB color-space - we used it to make an umbrella that matches whatever color it touches! (https://learn.adafruit.com/florabrella/) Since then, ams OSRAM has worked to create better light sensors that reduce the need for end-user calibration or a lot of microcontroller lifting. The chips have carefully tuned PN diodes to not only be able to report correct color values, but ideally also have little variation from sensor-to-sensor. The TCS3530 (https://www.digikey.com/short/qwt595fh) is the latest color sensor from ams OSRAM, and it's also their newest with XYZ color output! This means you can read CIE XYZ color values out directly from the driver, which is going to be the best way to model what a human eye sees (https://en.wikipedia.org/wiki/CIE_1931_color_space) - not just an optimal concept based on 'pure' RGB photodiodes. This makes it ideal for use with cameras, monitors, printers/copiers and other devices that have humans that are looking at the colors. By detecting ambient light temperature, monitors and camera sensors can adjust their white balance to have their color gamut appear more 'natural' even in yellowish incandescent or halogen, or blueish fluorescent light. The TCS3530 (https://www.digikey.com/short/qwt595fh) does this by having 8 separate PN diodes, each tuned to a specific frequency band, to cover from about 400nm to 750nm. The diodes are normalized by the ALS engine so that you don't get over-sensitivity to green or IR. The diodes are arranged in a 4-way symmetric array to get fully balanced readings across all frequencies: there's probably some reasoning to how the layout is done to avoid signal from one diode from affecting a nearby one, something ams has decades of experience with. A modulator and flicker detection system can sense light pulses such as those from incandescent bulbs (at 120 Hz) or monitors (30 to 60 Hz) so that we can sample at the same times during the wave, or sample long enough to capture a full waveform worth of light. Interfacing is fairly simple, although there are a few things to watch out for during integration. The sensor supports both I2C and I3C (https://www.youtube.com/watch?v=hC4zkvdVag4) so it's good for legacy or modern microprocessors. Note the chip requires no greater than 1.8V power and logic, so for 3.3V systems - a shifter will be necessary. Finally - the chip has a massive number of registers to tweak the settings. So while you could write a driver, you're probably best off using ams OSRAM's TCS3502 linux C kernel driver to base your implementation if you are not just using Linux/Android directly. If you want to add precision color sensing with pre-calibrated CIE XYZ outputs to your next design, the ams OSRAM's TCS3530 True Color Sensor (https://www.digikey.com/en/product-highlight/a/ams/tcs3530-true-color-sensor) is a top choice from a world leader in light sensing. And best of all, it's in stock right now at DigiKey for immediate shipment!

Psst...this week's EYE ON NPI is no secret, and despite having the word "Pseudo" in the name, it's the Real Deal: This week it's ISSI's Serial and Quad PSRAM chips (https://www.digikey.com/en/product-highlight/i/issi/serial-ram-and-quad-ram-solutions), an excellent addition to your next microcontroller board to quickly boost your RAM stack to megabyte proportions! Microcontrollers have come a long way since 8-bit chips like the ATmega328 (https://www.adafruit.com/product/123). What used to be a luxurious 32 KB of flash memory and 2 KB of SRAM is now nowhere-near-enough storage for handling the big computation requirements we're trying to squeeze into embedded products. It used to be enough to handle some buttons, blink a few LEDs, maybe at best read a sensor and control a motor. Now we need internet connectivity, full graphics support, and machine learning algorithms running on large sensor data sets! As we've seen, microcontrollers have evolved from 8-bit AVR to Cortex M0 to Cortex M4 and even M7 - or if you're a fan of Espressif chips, Tensilica/RISC-V 240 MHz processors. But what you are paying for in a microcontroller is often related to the density and size of the die, and on many processors, the RAM and FLASH can start to take up a dominant amount of die real-estate. SRAM and Flash may also require larger nm 'processes' that are harder to book. As a result, we're seeing chips like the RP2040 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0914-13/14306010) that have on-chip SRAM but no longer have on-chip Flash memory. Instead, you're expected to pick up a QSPI flash chip and wire it up to the 6-pin interface. By clever usage of on-chip instruction cache, you can get close to on-board FLASH speeds but with the flexibility and size of external memory: it's hard to find a chip with more than 1 MB of internal FLASH but you can easily get 16 MB of external memory like the ISSI IS25WP128 (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS25WP128-JBLE/5431600) for only a couple bucks! OK now you've got plenty of space for your code, but what about RAM? That's where you'll be buffering graphics, storing data to process, or for IoT products, storing large packets of data that may need to be encrypted before sending/receiving. SRAM is also big and kinda expensive, so it's no surprise that many advanced processors these days also support external RAM chips. Now, most folks aware that microprocessors (as opposed to microcontrollers) have required external RAM for quite a long time - but often those used large DRAM chips with 8, 16 or 32-bit parallel interfaces like the IS42 series (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS42S16400J-7TL/2708623). These of course are not going to work when you only have 32-ish GPIO available. That's where 8-pin PSRAM chips come in - and we're starting to see lots of 'low pin count' microcontrollers support these. For example the iMX RT1062 (https://www.digikey.com/short/0fhbdwv0) used in the Teensy 4.1 (https://www.adafruit.com/product/4622) supports PSRAM - check the SOIC-8 footprint on the bottom. Likewise the ESP32 series has wide support for PSRAM, their modules come with 8-SOIC 2MB chips very often. The extra PSRAM comes in handy when doing large IoT projects where you have to buffer an entire image, or JSON structure. Especially over TLS connections that require a lot of RAM to process! Note that while you could use the ISSI PSRAM chips with any processor, thanks to the generic SPI or QSPI interface, you really do want a chip to have 'native' PSRAM support so that the compiler and core will automatically map the PSRAM out so it is accessed transparently to your code. You'll likely need to enable PSRAM support in your toolchain and of course wire it up to the supported QSPI interface pins. Also, sometimes you need to be careful about where some memory goes, like volatile or interrupt-accessed addresses. Sometimes you also have to tell the compiler what ID code or command-set to use, since things like enabling the QEN bit can vary from chip to chip. With a universal pinout and speedy 100MHz clock rate, PSRAM is a fast and easy way to make your micro roomier. If you're not sure which to pick, maybe start with the IS66WVS2M8BLL (https://www.digikey.com/short/29b1dzqf) a 2 MByte / 16 MBit 3.3V-logic SOIC-8 PSRAM chip. If you're ready to add encyclopedic memory in your next design, you are in luck, because the ISSI Serial and Quad PSRAM chips (https://www.digikey.com/en/product-highlight/i/issi/serial-ram-and-quad-ram-solutions) are in stock right now for immediate shipment!

This week's EYE ON NPI will make you say "Yeee-haww", to the buckin'-and-boostin' bronco known as the Richtek RT6160A Buck-Boost Converter with I²C Interface (https://www.digikey.com/en/product-highlight/r/richtek/rt6160a-buck-boost-converter). The RT6160A is a high-efficiency, single-inductor, synchronous buck-boost converter that can provide up to 3 Amps of current to a dynamically-configurable voltage from 2.025V to 5.2V. With an amazing 2uA quiescent current, this chip lets you add an advanced power supply for the price of an LDO that will let you design with the smallest possible battery. We're big fans of Richtek for low quiescent power supply chips - our favorite 3.3V LDO is the RT9080-33 (https://www.digikey.com/en/products/detail/richtek-usa-inc/RT9080-33GJ5/6161634) which can provide up to 600mA with a 0.5V dropout, and a really nice 4uA quiescent current. This is great for deep-sleep wireless projects where you've got a chip with ultra-low power snooze modes, like the ESP32 - we were able to get down to 10.5 uA in deep sleep thanks to the RT9080! (https://learn.adafruit.com/adafruit-itsybitsy-esp32/low-power-use). Compare that to the AP2112K which we used to use, has a quiescent current of 55uA. However, the RT9080 is a LDO fixed at 3.3V@600mA - and of course, LDOs have that dropout which translates to power lost. If you want to sip every last Coulomb out of the battery on hand, you'll need a DC/DC converter. Usually we see a buck converter - since you are converting from a Lithium Polymer battery, you'll have 3.7V nominal, 4.2V peak voltage and maybe you'll buck that down to 3V. If you want to really get the best possible range of performance, you can go with a buck boost (https://en.wikipedia.org/wiki/Buck%E2%80%93boost_converter). That way you can buck down from 3.4-4.2V and then as the battery starts drooping, the chip switches into a boost mode to cover the 2.7V~3.2V range. The RT6160A is a Buck-Boost converter that seems well designed for battery-powered projects, with an input and output range of about 2 to 5V. The default output is 3.3V and you can 'select' between two voltages by toggling a GPIO pin. This makes it easy to adjust the desired voltage and then swap from 'high' to 'low' voltages without an I2C command. Why would you want two voltages? Well, you could use 3.3V or greater for when you want the best performance from a radio, then drop down to 2.5V when the radio isn't on and you want to reduce both the conversion current and also reduce your chip quiescent current: most microcontrollers will use lower current at lower voltages since they are not pushing around as much current onto the internal logic FETs. Combine this with a microcontroller's dynamic clock frequency configuration and you've got a simple system to squeeze more current out of your battery. And usually you have to 'spend' a lot of current to run the DC/DC converter, but this chip has an amazing 2uA quiescent current - lower than most LDOs we've used, and amazing for an up-to-3A output device. If you want to have the lowest quiescent, highest-flexibility power management chip in your next design, the Richtek RT6160A Buck-Boost Converter with I²C Interface (https://www.digikey.com/short/hv7fm4nt) is an excellent choice: Richtek really know their power supplies and they keep it nice and simple so you can get to integration instantly.

This week's EYE ON NPI is virtually the best chip you could get for VR tracking - it's the TS4631 Light-to-Digital Converter (https://www.digikey.com/en/product-highlight/t/triad-semiconductor/ts4631-light-to-digital-converter) a specialized mixed-signal ASIC that is designed especially for folks who want to design accessories for the SteamVR (https://store.steampowered.com/app/250820/SteamVR/) and specifically, HTC Vive hardware (https://www.vive.com/us/). Thankfully, this chip is available without restriction or NDA, which means it's theoretically possible for anyone to design tracking technology without the hard part of making the fixed-base-transmitters. Precision 3D tracking within a room is incredibly hard: Cameras can kinda do depth perception but they require a lot of computation and often make mistakes on object recognition. You can try using UWB but it's very pricey and has precision limitations. HTC Vive solves this by using IR light, which is not-sensitive to room illumination, doesn't have RF interference, and is fairly inexpensive. Each 'lighthouse' acts like a lighthouse: after an initial Infrared burst for sync, it sweeps IR over X & Y directions. Check out Alan Yates' detailed talk for how this design works (https://www.youtube.com/watch?v=75ZytcYANTA) The object being tracked has an IR photodiode, which catches the sync pulse, then measures the time between that and the X and Y sweeps. It does this for each lighthouse. With some fun matrix math (https://trmm.net/Lighthouse/), it can then calculate it's X Y Z coordinates with respect to the Lighthouses and, given we know the location of those Lighthouses during an initial calibration step, we can localize that IR diode within the fixed coordinates of the room we're in. That means that if you want a device that can detect the IR pulses and sweeps, all you need is an IR photodiode like the OSRAM BPW 34 (https://www.digikey.com/short/b5jn4pnp) and a bunch of analog electronics to filter out ambient noise, detect the carrier frequency, and give you the timing pulses detected. Or, you can save yourself a ton of effort, and just go with the Triad TS4631 (https://www.digikey.com/short/fwr173wh). All you need is the photodiode and a couple simple passives and you can have a configurable sensor analog front end at low cost and low complexity. In fact, that's what nearly all Vive-compatible hardware uses. (https://twitter.com/SadlyItsBradley/status/1634146181755355136) The Triad TS4631 (https://www.digikey.com/short/fwr173wh) comes in a compact 0.4mm-pitch 9-pin BGA package, which thankfully uses the center ball as a second ground so no buried vias are required. Give it 3.3V power, a BPW 34 S (https://www.digikey.com/short/p8j9r7z0) photodiode, and a couple passives for the power supply, and it's ready to go! There's two output pins for the Envelope and Data from the IR signal. Those two pins are also the I2C configuration pins, and you can use any microcontroller to read and write the configuration registers that let you set up the gain, thresholds and sleep modes. There's a library for the TS4231 (https://github.com/TriadSemi/TS4231) available from Triad, and since the TS4631 mostly improves the TS4231's power usage, you can likely start your microcontroller interfacing and development with that code. There's also lots of other folks playing around with the Triad TS4631 (https://www.digikey.com/short/fwr173wh) and TS4231 (https://www.digikey.com/short/fmcj4wft) which means that you can find hobbyist projects for design inspiration. We found some great info from famed hackers CNLohr (https://hackaday.io/project/153224-ts4231-esp8266-lighthouse-tracking) including libsurvive for desktop tracking (https://github.com/cntools/libsurvive/), Trammell Hudson (https://trmm.net/Lighthouse/), and other YouTube makers (https://www.youtube.com/results?search_query=ts4231). There's also a published project called HiveTracker (https://hivetracker.github.io/) that has hardware and firmware for a fully-designed tracker board with Bluetooth LE as the backchannel. If you want to get started with making 3D-trackable devices for VR or AR applications, it's great to not have to build the whole system from scratch. With the Triad TS4631, (https://www.digikey.com/short/fwr173wh) you can integrate into the existing SteamVR/HTC Vive ecosystem or you can chart your own path with their hardware and your own software. Either way, you'll want to pick up some TS4631's and you're in luck because DigiKey has them in stock right now, for immediate shipment!

This week's EYE ON NPI is one of a kind - it's the MPS MPM3510A 36 V 1.2 A Step-Down Converter from Monolithic Power Systems (https://www.digikey.com/en/product-highlight/m/mps/mpm3510a-36v-1-2a-step-down-converter). You might be asking yourself, "wait, is this the same Monolith that appeared in Kubrick's 2001 Space Odyssey (https://www.youtube.com/watch?v=ypEaGQb6dJk)?" Technically... no. But, we are talking about a new product that comes to you as a black oblong, and contains technology that will transform and evolve your schematic to the next level of existence. The MPM3510A and friends (https://www.digikey.com/short/5dv839jp) are part of the fully-integrated DC/DC converter family from MPS. These modules contain a step-down chip as well as an inductor - plus maybe a passive or two - to create a tiny buck converter that can take an input from 4.5V to 36V DC and convert it down to 0.8V to 36V, configurable with a resistor divider. Despite it's petite stature, it can source 1.2A, and as its an efficient DC/DC converter, no heatsink is required. With the high integration, you only need two resistors and two capacitors to complete the design. We first spotted these converters on Arduino boards like the Nano Every (https://www.digikey.com/en/products/detail/arduino/ABX00028/10239971) that need to be small and thin. Specifically, that's using the MPM3610A (https://www.digikey.com/en/products/detail/monolithic-power-systems-inc/MPM3610AGQV-Z/5292908), which is an earlier version of the MPM3510 which goes to 21V max instead of 36V. We also have a cute breakout for the MPM3610 with either 3.3V fixed (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4683/12822323) or 5V fixed (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4739/13175530) output. Files for those boards are available on GitHub under an open source license (https://github.com/adafruit/Adafruit-MPM3610-PCB) If you want to quickly integrate the MPM series, check out the downloadable footprints and 3D models available in the EDA Models page (https://www.digikey.com/en/models/7361650). And, even though layout is simple, you should still consult the datasheet to make sure you've got the right setup for the bulk capacitors and power fills, since 1.2A output is a fair amount. One trade-off of having such a small solution is that to get the combined package so small, the inductor has to be low inductance, which means that the PWM frequency of the DC/DC converter is 1-2 MHz. That means you won't be at the top of efficiency...for that you'd have to design a converter with lower frequencies and much bigger inductor. If you need more or less than 1.2A output, or a different range of voltages for inputs or outputs, there's a whole family available of MPM modules, from the diminutive 2mm x 2mm MPM3804 that works only up to 5V and 0.6A (https://www.digikey.com/en/products/detail/monolithic-power-systems-inc/MPM3804GG-Z/7361493) up the chonkin' MPM3686, with a 12x15x14mm body, and 20 Amps output. (https://www.digikey.com/en/products/detail/monolithic-power-systems-inc/MPM3686GRU/5298342) Thankfully, all these chips are yours to use! And, best of all, the MPS MPM3510A 36 V 1.2 A Step-Down Converter (https://www.digikey.com/short/5dv839jp) and friends are all in stock right now for immediate purchase from DigiKey. Order today and it will be shipped instantly, so that you can get your design completed and to market in record time: no worrying over your DC/DC converter design size, efficiency or component selection.

EYE ON NPI - Nexperia NPS4053 5.5 V Load Switch

Adafruit Industries

This week's EYE ON NPI will take a load off your mind, it's Nexperia's NPS4053 5.5 V Load Switch (https://www.digikey.com/en/product-highlight/n/nexperia/nps4053-5_5-v-load-switch) - it's Nexperia's first load switch and they did a great job with the NPS4053 which can be used for a variety of situations where you want to separate power supplies for protection or power savings. I'll admit, I've never used a load switch chip before - so this EYE ON NPI was a bit of a learning experience. Traditionally we've used 3 major ways to switch current. First is, of course, a simple switch - we use something like this on our QT Py Lipo BFF (https://www.adafruit.com/product/5397) where we want to allow mechanical switching and the amount of current isn't super high. The slide switch is specified for 300mA and we double-up the DPDT to allow for 600mA. This could be expanded upon with a power switch that can handle up to 240VAC and 5A (https://www.adafruit.com/product/3991) - but of course someone has to flip the switch. We could solve that issue by going with a relay or a solid-state-relay (https://blog.adafruit.com/2023/08/03/eye-on-npi-sensata-crydoms-series-1-ac-panel-mount-solid-state-relays-eyeonnpi-digikey-sensata-digikey-adafruit/) but they have some downsides as well: high cost, large space requirements. We need something much smaller! On our dev boards we have historically used two techniques for flipping on/off power to subcircuits. One is the P-FET high-side switch, which you can see on our Metro boards on the DC jack (https://www.digikey.com/short/d3j7z977). This method is classic, and works well but has a few downsides: you need a second transistor to control high voltages with a low voltage signal since the gate is pulled up to the high input voltage. Also, there's that built-in diode that is will conduct current from the output back to the input - you can see in our schematic how we also have to add a forward-diode to protect against that. Altogether, you would need 2 transistors, a diode and a couple resistors to make a FET-based switch. There's also another downside to FET switches, which is that they are not current limited, so if you happen to be switching a significant amount of current, it could cause a transitory spike on your main power supply...which causes a brownout! Something we experienced when we tried using a P-FET to switch on-off an I2C port. It worked great for low-current sensors but would crash the board when used with a 100mA-draw air quality sensor. So we used a fully separate LDO on the Feather ESP32-S2's (https://www.digikey.com/short/4nj457zb) - this works because we have a volt or more drop from the conversion from 5V to 3.3V so if there's a dip in the voltage, it isn't going to affect the main micro's power supply. This works because the LDO is only a few cents (https://www.digikey.com/short/fnr9jtnj), and we happen to have the headroom. It also has true-disconnect (no extra diode needed!) and is compatible with lower voltage logic signals. But, most devices have a DC/DC converter which is going to be a lot larger than a SOT-23-5 LDO - and there might not be as much headroom. That's where the Nexperia NPS4053 5.5 V Load Switch (https://www.digikey.com/short/ttjt5mjw) comes in! It combines all the analog electronics you need to easily switch loads of up to 5.5V at 2A, with all the niceties that you'd normally have to manage by hand. Instead of a second diode, it has true-cutoff. Instead of a separate current-limiting circuit (https://en.wikipedia.org/wiki/Crowbar_(circuit)), you can set the current limiting with a resistor and the load switch will turn from Constant Voltage to Constant Current mode. The chip also handles transients nicely, with soft-start, so that you don't get a shock to the power supply if the sub-circuit turns on all at once! In addition, there's Under Voltage Lockouts and short circuit protection. If something does go wrong, the chip will disconnect the load and drive the FAULT pin low, so you can communicate to the user that something is amiss. For many of the short/temp/over-current errors, the chip will naturally recover. With an adorable 2x2mm HVSON package and a cost of only 20 cents in quantity, the Nexperia NPS4053 5.5 V Load Switch (https://www.digikey.com/short/ttjt5mjw) will fit into the same board slot as a transistor for not much more, and replace a ton of power management circuitry with elegant simplicity! And, best of all - it's in stock right now at DigiKey for immediate shipment, in both commercial/industrial (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NPS4053GHZ/21286453) and Q100Z variants (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NPS4053GH-Q100Z/21286452).

EYE ON NPI - Nexperia Battery Life Booster ICs

This week's EYE ON NPI is going to give you life, we're looking at Nexperia's Battery Life Booster ICs (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics), an interesting solution for dealing with common coin cell batteries as an inexpensive power supply for your small electronic products. The marketing copy for this chip series is pretty eye-catching, with copy that they are "designed to extend the life of a typical lithium coin cell battery by up to an order of magnitude (10x) while also increasing its peak output current capability by up to 25x" (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics) Quite a claim! So let's take a look at what this chip can really do, and why we need it to help with our coin battery-powered designs. Primary Lithium LiMnO2 coin batteries (https://www.digikey.com/en/products/filter/battery-products/batteries-non-rechargeable-primary/lithium-manganese-dioxide/90) are hard to beat when you want ultra-dense, low-cost power that is very small. They are the smallest form factor of user-serviceable battery. And the power density of coins - plus their flat shape - makes them great for wearable devices, medical sensors or hearing aids, wireless nodes, anything that is smaller than a finger. With a nominal voltage of 3VDC, and 280 Wh/kg density, they are more dense than a AA alkaline. LiSOCl2 batteries (https://www.digikey.com/en/products/filter/battery-products/batteries-non-rechargeable-primary/lithium-thionyl-chloride/90?s=N4IgjCBcoCxgTFUBjKAzAhgGwM4FMAaEAeygG0QBmANgFZKEQBdIgBwBcoQBldgJwCWAOwDmIAL6SgA) are even more dense, with 3.6V nominal and 500 Wh/kg - twice the density of LiMnO2 or Alkaline. Both are non-rechargeable batteries, and while fairly inexpensive when bought in bulk, they can add up in cost when buying from a grocery store, so making sure that they last a long time is essential for a good customer experience. The Energizer Lithium Coin Handbook and Application Manual (https://data.energizer.com/pdfs/lithiumcoin_appman.pdf) is chock full of good advice for folks who want to use a CR2032 or similar coin battery to power their products. It's written with engineers in mind, so a lot of the document covers how the nominal voltage and current, 3V and 240mAh, are deeply affected by shelf life, internal resistance, temperature, and pulse effects. The biggest downside you will see on coin batteries is their relatively high internal resistance - IR. Whereas alkaline and LiPoly batteries have internal resistance well below 1 ohm, the IR of a CR2032 is 9 ohms. So say you want to draw 100mA from a CR2032, even if just for a few millisecs - that 0.1 A turns into a .9V drop across the IR which means what you thought was a 3V power supply is now 2V - too low for your microcontroller or radio to run. Since the power lost across the IR is 2*I*R and R is fixed, it's doubly important that you keep that I low, so that you can minimize IR loss and use as much of that 700mWh stored energy. In our 100mA example, 30% of the battery energy is lost to resistor heat dissipation! That's where Nexperia's Battery Life Booster ICs (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics) come in. They are designed to be used with products that don't need continuous battery drain, that is they have a very low duty cycle where the user presses a button a few times a day or maybe the sensor node transmits only once a minute. During that short transmit or usage cycle, a radio or LCD display may need up to 200mA but its for a very small amount of time and the voltage needs to be stable. The NBM family of chips do this by slowly sipping a small amount of current from the battery, keeping that I low so that the 2*I*R power loss is minimized, then use that constant current to boost a voltage onto a large storage capacitor. The capacitor is chosen to have high capacitance and high voltage for a large total Joule storage capacity. All four variants of the Nexperia NBM family, NBM7100A (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM7100ABQX/19109915), NBM5100A (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM5100ABQX/19109703), NBM7100B (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM7100BBQX/19110140) and NBM5100B (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM5100BBQX/19109874) are in stock right now at DigiKey for immediate shipment!

The UNO R4 comes in two flavors, the Minima (https://www.digikey.com/short/r70jbj93) is low cost, only $20, whereas the UNO R4 WiFi (https://www.digikey.com/short/qj072pnm) is $27.50 and adds WiFi and BLE via an ESP32-S3 plus a cute monochrome LED grid for scrolling messages or displaying status icons. This pair of dev boards look just like those classic Arduino boards you probably learned to code and hack on, they've been around for almost 20 years, the first board looked very similar, but had a RS232 serial port instead of USB, and all through-hole components (https://blog.arduino.cc/2021/12/09/one-board-to-rule-them-all-history-of-the-arduino-uno/). Through various iterations and improvements, the original board was redesigned to add USB and update to the ATmega168 with the Diecimila (https://docs.arduino.cc/retired/boards/arduino-diecimila) and then the ATmega328 plus auto-power-switching Duemilanove (https://docs.arduino.cc/retired/boards/arduino-duemilanove) in 2009. In 2010 the most popular Arduino to date was released, the UNO, which updated the USB port to use an ATmega16u2 and through various small revisions added the IOref pin to allow 3V power/logic and separate I2C pins since A4/A5 were no longer always connected to a TWI peripheral. Since about 2012, which was the release date of the UNO R3, not a lot has happened with that particular configuration/shape. Arduino the company has released a ton more boards but in different form factors, all available at DigiKey: Nano, Due, MKR, Portenta etc. (https://www.digikey.com/en/supplier-centers/arduino) and you should definitely check them out! But it's also a big deal when the main workhorse of the family gets a respin. Particularly since the new R4 takes a very different direction than the previous UNOs: instead of just upgrading the atmegaxx8 chipset, Arduino has gone with the totally different ARM Cortex-based RA4M series which we've covered on a previous EYE ON NPI (https://blog.adafruit.com/2023/05/25/eye-on-npi-renesas-ra4m1-microcontroller-series-eyeonnpi-digikey-renesasglobal-digikey-adafruit/) In that video we covered a lot about the chip itself so check it out if you're interested in the specifics of that chip family. The chip itself is a similar family to the ARM Cortex M0-based SAMD21 'Arduino Zero' (https://store-usa.arduino.cc/products/arduino-zero?selectedStore=us) but thanks to the Renesas version of this core, we now get the 5V-run RA4M. From Arduino's description, here are some of the updates: - Hardware compatibility with UNO form factor: The UNO R4 Minima maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3. This ensures a seamless transition for existing shields and projects, leveraging the extensive and unique ecosystem already established for the Arduino UNO. - Expanded memory and faster clock: Prepare for more precise calculations and the ability to handle complex projects with ease. The UNO R4 Minima boasts increased memory and a faster clock speed, empowering you to tackle demanding tasks effortlessly. - Extra on-board peripherals: The UNO R4 Minima introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP. These additional components provide you with expanded capabilities and flexibility in your designs. - Extended 24 V tolerance: The UNO R4 Minima now supports a wider input voltage range, allowing power supplies up to 24 V. This enables seamless integration with motors, LED strips, and other actuators, simplifying your projects by utilizing a single power source. - SWD connector: Debugging is a critical aspect of any project. Simply connect an external debugger to the UNO R4 Minima and effortlessly monitor the inner workings of your system. Stay in control and gain valuable insights. - HID support: The UNO R4 Minima comes with built-in HID (Human Interface Device) support, enabling it to simulate a mouse or keyboard when connected to a computer via a USB cable. This convenient feature makes it a breeze to send keystrokes and mouse movements to a computer, enhancing usability and functionality. At $20 a piece, these new Arduino UNO R4s (https://www.digikey.com/short/qj072pnm) are a great price for the high quality you get from Arduino - and there's lots of them in stock at DigiKey for immediate shipment!

Buck-Boost Converters are power supplies that are 'ambidextrous' - they can convert lower or higher voltages to one steady output. A good idea for if, say, you have something that could be powered by USB or two AA's but you want 3.3V output. Much like the name implies, they can both 'buck' the voltage down, and 'boost' the voltage up. For our Toy Hacker board, let's try to find a low cost buck-boost chip that will give us about 500mA of 3.3V output even from two nearly-dead AA batteries that are 0.9V. We want something somewhat small and fairly inexpensive, efficiency isn't the most important since we expect folks to use rechargeable AAs anyhow.

This week's EYE ON NPI is going to fuel up your portable battery-powered designs with the Texas Instruments BQ27427 System-Side Impedance Track™ Single-Cell Battery Fuel Gauge (https://www.digikey.com/en/product-highlight/t/texas-instruments/bq27427-single-cell-battery-fuel-gauge) a powerful and inexpensive way to add high quality battery monitoring for charge-rate and aging tracking at the system side. Lithium Ion / Polymer batteries (https://www.digikey.com/en/products/filter/batteries-rechargeable-secondary/91) - you love them for their low cost, high power density, and 3.7V nominal voltage, but keeping them recharged and letting people know exactly how much battery life is left is non-trivial. Like most batteries, common LiPoly/LiIon's start with a high peak voltage right after charging of about 4.2V, drop quickly to about 3.7V and then slowly drift down till they get to 3.0V at which point the cut-off circuitry disconnects until they are recharged. It's really easy to tell when the battery is 90% or greater charge, just look for a voltage of 3.9V or higher. It's also pretty easy to tell when they're 10% or less, the voltage will be 3.3V or lower. But that in-between section is tough because the slope during discharge is very shallow and the voltage changes quite a bit with aging, temperature, and discharge rate (https://www.ti.com/lit/an/snva533/snva533.pdf) So while there are battery monitors that can use just the voltage across the battery terminals, they're not going to be as precise as a coulomb-counter design that takes into account both voltage and current. From TI's White Paper on the topic (https://www.ti.com/lit/wp/slpy002/slpy002.pdf): "An impedance-based battery fuel gauge, as the name implies, uses the measured impedance of the battery's cells as a key input to its remaining capacity predictions. The gauge measures and stores in real-time the battery pack's resistance as a function of state-of-charge. The real-time resistance profiles along with the stored battery open-circuit voltage tables (open-circuit voltage vs. state-of-charge) enables the gauge to predict the battery pack's discharge curve (by adjusting for the IR drop) under any system-use condition and temperature. The algorithm uses current integration (coulomb counting) when the system is ON, and open-circuit voltage measurement when the system is OFF or in SLEEP to adjust remaining state-of-charge (RSOC) up or down (for charge or discharge) the predicted discharge curve. By using the predicated discharge curve, the gauge can accurately calculate the battery pack's remaining discharge capacity (RM) and the system's run-time to empty (RTTE). Since an impedance track gauge continuously adjusts RM and FCC for impedance and the change in impedance, rate and temperature inefficiencies and aging are inherently taken into account, enabling the gauge to maintain a high level of accuracy throughout the life of the system." Texas Instruments has a few chips in the Impedance Track family (https://www.ti.com/video/6287050244001) - the BQ27427 charger (https://www.digikey.com/en/products/detail/texas-instruments/BQ27427YZFR/17748369) is the latest to come out. It's very small, coming as a 9-pin 1.6x1.6 BGA with the center pad being a shared ground so you don't need plugged vias to use. It's also really easy to use, requiring only 2 small stabilization capacitors. Internal temperature monitoring means you don't need a separate thermistor. The high-side 7 mΩ current sense resistor also means one less part on the BOM. I2C pins are used to communicate with the monitor and set battery characteristics. There's also an optional input that can be used to connect to a mechanical or electrical battery insertion switch or to an external thermistor, and an optional output that can be used as a battery low indicator. Because so much is integrated, and the chip is so small, its very easy to pop it into your design between the battery terminal and the VBAT lines that go to your battery charger and power supply. The peak battery voltage and capacity are easy to look up since they're written on the battery. For other configuration settings you can use BQStudio / GaugeStudio (https://www.ti.com/tool/BQSTUDIO) with the TI battery devboard to characterize and customize the learning cycle. Either way, you will need to write the configuration to the sensor on every boot. Pick up the Texas Instruments BQ27427 (https://www.digikey.com/short/18pb1ftw) and other chips from the Impedance Track family (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANrhwCsAnBALqEAOALlCCAF8hQA0) stocked at DigiKey for immediate shipment.

This week's EYE ON NPI is enjoying the beautiful weather with you, whether sitting in the sun or lounging in the shade - all's good because we've got Nexperia's NEH2000BY Energy Harvesting Power Management IC with embedded solar MPPT capability! (https://www.digikey.com/en/product-highlight/n/nexperia/neh2000by-energy-harvesting-power-management-ic) This tiny, low-cost chip is a one-stop solution for extending the life of your product by making it powered by small solar cells. This chip is perfect for wearables or miniature sensor nodes, maybe with a LoRa radio, WiFi or Bluetooth Low Energy where space and pricing is important. For example, an asset tracker, traffic monitor, activity watch, or agricultural sensor network: stuff that is outside anyways so it'll be designed for outdoor use and have lots of sun exposure. We've covered other MPPT tracking solar harvesting chips (https://blog.adafruit.com/2021/04/23/eye-on-npi-max20361-tiny-single-multi-cell-solar-harvester-maximintegrated/), and the NEH2000BY has some advantages in size, cost and simplicity. Either use it to increase the time between charges, or use it to have your product be fully encased with no need for charging at all, thanks to the power of the SUN (https://solarsystem.nasa.gov/solar-system/sun/galleries/?page=0&per_page=25&order=created_at+desc&search=&href_query_params=category%3Dsolar-system_sun&button_class=big_more_button&tags=sun&condition_1=1%3Ais_in_resource_list&category=51) The Nexperia NEH2000BY energy harvester (https://www.digikey.com/short/hpnfttw3) is designed specifically for use with solar cells because cells collapse under high current draw - which is what batteries want when they are charging up so that they can be ready to go ASAP! When drawing current from a solar cell, at the very beginning the voltage is very high, then is slowly drops down as more is drawn until the input voltage collapses completely. So you have to be very careful when drawing current - too little and you lose out on efficiency, too much and your power goes away completely. There's a 'sweet spot' right in the middle, where you can get the most power output, which is called the Max Power Point. (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) And this point varies with how much sunlight you get - so it isn't something you can pre-program in with a comparator or anything. Instead, the energy harvester has to wiggle the power draw forward and back to find the maximum point. For large-scale solar installations, you'd have a microcontroller do the math for you, and adjust throughout the day - it isn't hard to do MPPT it just takes measurement and computation. But in small and low-current situations, you can't spend all your power budget on a microcontroller to manage your battery charger. First up, almost no extra components are needed: just a stabilization capacitor plus a capacitor for the switched-cap boosting doubler. Note that there's no inductor because it seems to use a switched-cap boosting method for approximately 2x voltage output - so you will need to spec a panel that, when the MPPT voltage is approximately doubled, you'll have about 0.3V above the battery voltage. There's some math in the datasheet to work this out but basically in the end, use a panel with an open-circuit voltage - Voc - that is about 0.7 times the battery voltage. So, e.g. if you're using a Lipoly (https://www.digikey.com/short/h02tmj1q), with a VBat of 4.2V, use a 3V solar panel - which is very common and inexpensive. For NiMH cells, add up the total series voltage before multiplying by 0.7 for the Voc desired. To keep your battery from over-charging, either use a separate battery charger chip that will do the constant-current to voltage-limited charging, or use a low cost over-voltage protection (OVP) chip as recommended in the datasheet. If you'd like to integrate the Nexperia NEH2000BY Energy Harvesting Power Management IC (https://www.digikey.com/short/hpnfttw3) into your next solar-powered product, thank your lucky stars because DigiKey has the NEH2000BY in stock right now at a great price for immediate shipment. With the long summer days ahead, you can order today and be max-power-point'ing before the sun sets tomorrow.

NeoPixel LEDs (a.k.a WS2812 / SK6812 family) are a super-easy way to add addressable RGB lighting with only one GPIO. they're ubiquitous on microcontrollers, but some chips or SBC's dont have neopixel support due to the precision timing required to send data. we often get folks asking how to get NeoPixels working on some OrangeBananaOnionRockchipAllWinner Pi type board, given we have our Blinka library that provides support for CircuitPython libraries. but if theres no neopixel_write implementation written for that platform, it just wont work. a quick solution is this seesaw-based NeoDriver board: send it the NeoPixel data you want to write over I2C and it will blit out the perfect pixel timing on the other side. we're using an attiny1616 so we have enough RAM to buffer a 512-pixel long strand. now, to be fair - its not super fast because we have to write each pixel over I2C https://learn.adafruit.com/adafruit-seesaw-atsamd09-breakout/neopixel, but with 1MHz clock and as long as you're not writing the whole strip at once, its not so bad! we add a 5V charge-pump so even on 3V boards, you'll get a clean 5V signal. pre-soldered terminal blocks and Stemma QT plugs make this a no-solder solution for adding NeoPixels easily to any device with I2C.

This weekend we whipped up a quick FUSB302 (https://www.digikey.com/en/products/detail/onsemi/FUSB302MPX/5844455) breakout that will allow USB Type C sink power negotiation. Basically, we can plug into a USB hub or wall wart that can provide up to 20V and request that much voltage. This could be really handy for audio or robotics projects that need 9V, 12V, 15V or 20V without the fuss of finding a matching DC adapter. Now that we've got the chip, the datasheet lets us know that we need a separate, external 3.3V-ish regulator to supply power to the chip. Let's go looking for an LDO that can handle 5V-20V in, and provide 3.3V and at least 100mA, along the way we'll also check that we have voltage-rated components and also chat about LDO versus buck converters for this use case.

This week's EYE ON NPI is a 1040 that is easier than filing out a 1040-EZ (https://www.irs.gov/filing/free-file-fillable-forms/free-file-fillable-forms-choose-the-right-1040-form), but will still get you a great return on your time investment: it's the NXP i.MX RT1040 Crossover MCU series (https://www.digikey.com/en/product-highlight/n/nxp-semi/i-mx-rt1040-crossover-mcu) an ultra powerful microcontroller that is designed to make it easy to add high speed processing without a lot of work or excessive BOM costs. The RT1040's ease of usability and implementation stands out when we look at the details, allowing you - yes you! - to have 500 MHz+ Cortex M7 processing on a low cost two layer board, and without a separate PMIC. We're featuring this chip as the big sister to the Metro M7 (https://www.adafruit.com/product/4950) that we're also releasing this week, so it's definitely an iMX party here at the 'fruit. The suggested way to program the iMX NXP series is to use NXP's IDE MCUxpresso (https://www.nxp.com/design/software/development-software/mcuxpresso-software-and-tools-:MCUXPRESSO) but you can also just use the NXP SDK with the arm-gcc toolchain in a command line or other IDE (https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain) If your application plans to use USB, we recommend checking out our TinyUSB implementation which has iMX RT10xx support (https://github.com/hathach/tinyusb) which compiles under arm-gcc as well, and includes many examples that you can build off of. We've also ported our TinyUF2 second-stage USB bootloader that has mass-storage for read-write of the flash memory (https://github.com/adafruit/tinyuf2). These chips are powerful and very integrated, so you don't need separate power management chips - also known as PMIC's - or SRAM but there are some tips and tricks to watch for about pin usage, the built in bootloader, and configuring the DC/DC converter. This handy video from NXP has some good quickstart tips (https://www.youtube.com/watch?v=mpb_mZknqrk) and each chip also has a suite of app notes for hardware implementation (https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/i-mx-rt-crossover-mcus/i-mx-rt1040-crossover-mcu-with-arm-cortex-m7-core:i.MX-RT1040). There's many chips in the iMX RT family, as you move up and down you'll be trading package size, SRAM, and peripherals, for complexity and price. (https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/i-mx-rt-crossover-mcus:IMX-RT-SERIES) The RT1040 sits nicely in the middle with 512KB of SRAM (the bigger chips are up to 1 or 2 MB), parallel TFT support, CAN bus, Ethernet, and two flexIO peripherals that can mimic various interfaces. But it doesn't have MIPI support, or a built-in camera interface, or a second USB port. Digi-Key does stock all of the rest if you so wish! (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogBMADAJxMDsIAuoQA4AuUECAC%2BYoA) The NXP evaluation boards are fully featured and are recommended by NXP to get started (https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXRT1040-EVK/17141404) We tend to develop off the eval boards first, then using the schematics as a guideline for our own designs. While the BGA packaging is intimidating, it's available in two sizes: 9x9 and 11x11 with the same pinout - the smaller one has 0.65mm ball pitch, and the larger one has 0.8mm pitch, which means you can fan-out on a 2-layer PCB (https://www.nxp.com/docs/en/application-note/AN10778.pdf) or get roomy with a 4-layer. Other than a 3.3V power supply, a crystal and some passives, you only need a QSPI flash memory chip - we use the W25Q64 (https://www.digikey.com/short/0jpf8wmf) on our Metro M7 with great success. Best of all, both versions of the NXP iMX RT1040 chips are in stock right now for immediate shipment from Digi-Key! We suggest starting with the larger MIMXRT1042XJM5B (https://www.digikey.com/short/jv9qjdtv) and the RT1040 EVK (https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXRT1040-EVK/17141404) Huzzah, the chip shortage is over - so order today and you'll be blazing along with a Cortex M7 at 500 or 600 MHz by tomorrow afternoon.
