This week's EYE ON NPI is all about isolation (https://www.youtube.com/watch?v=6x-Nl3_L1pA), it's the XP Power PBT02F Series 2 W DC/DC Converters with SMD Footprint (https://www.digikey.com/en/products/base-product/xp-power/1470/PBT02F/737947)! A compact and easy way to add power isolation to your design without having to muck around with transformer matching and isolation testing. We've covered lots of power supply solutions on EYE ON NPI (https://blog.adafruit.com/tag/eye-on-npi/) including bucks (https://www.youtube.com/watch?v=sEoM5vUjwwI), boosts (https://www.youtube.com/watch?v=2NJzL0jCmfU) and even buck-boosts (https://blog.adafruit.com/2024/08/09/eye-on-npi-analog-devices-max77859-buck-boost-converter-eyeonnpi-digikey-digikey-adi_news/) but we haven't yet covered an isolating chip/module. However, they're so useful when you want to make sure that your electronics are not connected directly to a power supply or Earth ground. This could be for safety reasons: you want to make sure that there is no way for a high voltage from the input to somehow make its way into the output. Or it's used to make sure that a DAQ doesn't have a ground loop. Or maybe you're measuring/controlling a high voltage system from a low voltage - isolating power and data is essential. And speaking of, we often do have to isolate both data and power! Remember that digital and analog signals are always ground referenced so it's no good to have just data or just power isolation: you need them both! Data isolation is a lot easier than power though: you can use optical a-la your common optoisolator (https://www.digikey.com/en/products/category/optocouplers-optoisolators/2058), capacitive (https://www.adafruit.com/product/4903), or even chip scale micro-transformers (https://blog.adafruit.com/2024/03/14/eye-on-npi-analog-devices-adum1252-3-bidirectional-i%C2%B2c-isolators-eyeonnpi-digikey-digikey-adi_news-adafruit/). We have more flexibility because we only have to transfer signal, not actual power: all of those techniques assume that the 'opposite side' of the converter has isolated power ready to go. But that means that we have to do the hard part of actually transferring power over an air-gap. Now if you happen to be isolating AC power, say from 120V or 240V AC mains, this is super easy: just stick a transformer on there (https://en.wikipedia.org/wiki/Transformer) and you'll magically get isolation with the benefit of also being about to step up or down the voltage. But transformers don't work with DC, so what engineers have to do is create a buck/boost converter that uses a transformer instead of a plain inductor, thus creating the isolated flyback (https://www.xppower.com/storage/documents/technical-articles/PSUTopologies.pdf), a low cost way to transfer a couple watts. The XP Power PBT02F Series (https://www.digikey.com/short/5nh10cq0) come in a few variants, thanks to the built-in buck/boost converter topology. You can input voltages from 3 to 24VDC and get 3 to 15V out. There are even versions with 'split' dual outputs: a nice bonus from having a mid-tapped transformer (https://en.wikipedia.org/wiki/Center_tap) that can give you a centered ground reference. And one of my favorite things about it is that the whole transformer-DC/DC comes in a mini sealed pick-and-placeable package that is only 0.5" x 0.42" x 0.35", about the size of a coffee bean! Note the dual-output version is a little chunkier at 0.6" long - maybe like a chocolate-covered coffee bean. If you need a ultra-compact isolating power supply solution with buck or boost capabilities, the XP Power PBT02F Series (https://www.digikey.com/short/5nh10cq0) is going to satisfy your requirements! Available in a variety of options (https://www.digikey.com/en/products/base-product/xp-power/1470/PBT02F/737947), we're going to check out the PBT02F05S05 5V in/out (https://www.digikey.com/short/5nh10cq0) for our next USB isolation project. Best of all, it's in stock right now for immediate shipment from DigiKey! Order today and you will be designing and testing your power supply by tomorrow morning.

We've received several requests to update our low/full-speed USB isolator breakout, which used the ADUM4160. Low speed is for peripherals like mice and keyboards, where bandwidth demands are minimal. Full speed suits microcontrollers, audio interfaces, and simple USB accessories. High speed is needed for flash drives, video devices, data acquisition units, and external disks. Unsurprisingly, there's demand for high-speed isolation. We're now exploring USB isolation ICs that support high-speed performance. Stay tuned!

Last week, we conducted a Great Search for a clear shaft linear potentiometer. This week, the prototypes arrived—and they work great! We're also beginning work on the FruitJam Tester. We'll be showing the finalized silkscreen, the cover plate we designed, and the expected form factor of the tester itself. Additionally, we wrapped up a library for a QMC5883 breakout. This chip serves as a drop-in replacement for the now-discontinued HMC5883. It's frequently found in quadcopter builds, so we thought it would be a great candidate for a simple magnetometer breakout.

This week's EYE ON NPI is tick tock o'clock, it's the Abracon Real-Time Clock with Integrated 32.768 kHz Crystal Oscillator (https://www.digikey.com/en/product-highlight/a/abracon/real-time-clock-with-integrated-32-768-khz-crystal-oscillator). It's a tiny and affordable all-in-one RTC that has everything ya want, and nothin' ya don't. With it's compact package size, it's half the BOM size of what most RTC's need, and has a high quality Abracon crystal (https://www.digikey.com/en/supplier-centers/abracon) already included! We've been using Abracon (https://www.digikey.com/en/supplier-centers/abracon) crystals and oscillators in our designs for decades - for example a 12.288 MHz Crystal (https://www.digikey.com/short/w2qvtnbr) adorns our VS1053 breakout board (https://www.adafruit.com/product/1381). That's not the only thing they're good at, but it's the name recognition they've got as a trusted supplier of quality, affordable crystals and oscillators. So it was not surprising for us to learn that they now have an integrated-crystal real time clock chip for sale. Real time clock chips are specialty low-cost chips that keep track of 'real time' (e.g. the month, day, year, hour, minute, second) so that the rest of the system can go into shutdown mode or lose power, without losing track of time. They also often have alarms so that the system can reboot out of deep sleep to perform some task at an assigned delay or timestamp. As you might expect, the important characteristics to look for in an RTC are accuracy - how close their internal timekeeping is to true time - and power draw - how long they can run off the secondary power source such as a super-cap or coin cell battery (https://www.digikey.com/en/products/detail/panasonic-energy/CR-1025-BN/269738). There's other characteristics that you may care about: the voltage range they can power off of, whether they support a secondary battery backup with auto-switchover, and of course the interface and capabilities like alarms The AB-RTC-XB-32.768KHZ-2-T3 (https://www.digikey.com/short/tp4tjzqz) has many of the things we like to look for in an RTC. First, is a standard I2C interface - most RTCs are, and this makes it easy to add to any microcontroller or microcomputer. Second is a wide operating voltage range for power and logic: 1.2V to 5.5V with both a power and IO power pad! That means it's great even for low voltage cores or 5V Arduino-compatibles, and you can have separate voltages if desired. Alongside those two pins there's also a separate VBat pin for backup battery with auto-switchover. That means when the main power cuts off, say because USB got unplugged, or the main Lipoly battery is drained, we'll switch over to a coin cell or super-cap. Of course, the big feature of this RTC is the built-in crystal. By integrating directly, they're able to have an SMT chip with no external crystal in a 3.2 x 2.5mm package - the same size as most crystals! According to the datasheet, the crystal has a 5 ±23ppm frequency stability at room temp 25℃. That translates to 28 ppm max: 86,400 × (28/1,000,000) = 2.42 seconds gain/loss per day. At the typical 'best case' of 5ppm, its 86,400 × (5/1,000,000) = 0.432 seconds per day. That's in-line with most RTC crystal specifications, although it wouldn't be considered 'high precision' since its not temperature compensated. Temp compensation is much more complex and expected, and most RTCs will get auto-sync from the controller via WiFi/BT/GPS to apply correction every day~month to get them back on track. If you need a compact real time clock with a flexible power supply setup and Abracon-quality crystal, the AB-RTC-XB-32.768KHZ-2-T3 (https://www.digikey.com/short/tp4tjzqz) is an excellent new product offering that's available and in stock at DigiKey right now! Order today and before your morning alarm goes off you'll have this chip in hand and ready to integrate into your next product design.

Every week we'll 3D print designs from the community and showcase slicer settings, use cases and of course, Time-lapses!

Over the weekend, we set up our massive LED netting: https://www.digikey.com/en/products/detail/adafruit-industries-llc/6159/25981352. Even with current limiting in the Sparkle Motion/WLED setup, the power supply was browning out. Time to find a proper 12V supply rated for at least 15A—something beefy but safe and household-friendly.

For our synth project, we're looking for 6–7 general-purpose potentiometers to control parameters like envelope, resonance, and volume. Our last synth used the now-discontinued EVU-F2LFL3B54: https://www.digikey.com/en/products/detail/panasonic-electronic-components/EVU-F2LFL3B54/243639. Now we're hunting for a low-cost, through-hole linear pot—maybe even one with a little extra flair.
