This week we got a request to update our CAN Featherwing (https://www.digikey.com/short/wd08n1ft) and CAN BFF (https://www.digikey.com/short/dtjdhvtw) to support CAN FD (https://en.wikipedia.org/wiki/CAN_FD) - that's a v2 of the classic CAN interface and is pretty much standard now. The biggest upgrade is FD has Flexible Data rate, so you don't have to have perfectly sync'd data. Let's find something with SPI interface, and CAN FD support.

This week we designed some prototypes: CAN FD version of our FeatherWing and BFF. We also designed a board for the AP33772S (https://www.youtube.com/watch?v=ngQT0Et32wM) which we covered on EYE ON NPI - this is a chip that can do extended range USB Type C Power Delivery (https://www.usb.org/usb-charger-pd) and it seems, Programmable Power Supply mode (https://hackaday.com/2025/03/24/pps-is-the-hottest-usb-c-feature-you-didnt-know-about/). Might also do one for the AP33771C (https://www.digikey.com/short/022nd0fp) too with li'l switches like our HUSB238 (https://www.adafruit.com/product/5991). We also wrapped up the STHS34PF80 driver (https://github.com/adafruit/Adafruit_STHS34PF80) and we'll have a breakout for that shortly once we get chips on order. And on The Great Search: CAN-FD update to MCP2515

This week's EYE ON NPI will extend your power supply options, it's Diodes Inc's AP3377 series USB PD3.1 Sink Controllers (https://www.digikey.com/en/product-highlight/d/diodes/ap3377-usb-sink-controllers) a pair of chips that take the USB Type Power Delivery Sink specification to new highs with extended voltage ranges and two methods of configuration: the AP33772S (https://www.digikey.com/short/59d9mbvm) has I2C control interface while the AP33771C (https://www.digikey.com/short/022nd0fp) has two resistors to set the voltage and current limit. We've covered USB Power delivery sink controllers on EYE ON NPI before (https://www.digikey.com/short/59d9mbvm) with chips that can be configured to request higher voltages than 5V from a USB port. This is a boon for getting rid of DC jacks with various voltage and current ratings. It also helps prevent accidents where folks plug in a 12V power supply into a 5V port just because the plug is the same size. With classic USB power delivery, the client device communicates over the CC pins to the upstream computer or power plug to request any of the standard voltages: 5V, 9V, 12V (optional), 15V, or 20V and from 1A up to 5A. With software negotiation, the sink can figure out what power supply voltages are available then accept or reject to get the best power supply efficiency and performance. As we see adoption across many industries to use standard USB C, the power needs have also been expanded! As of USB PD v3.1 there is now Extended Power Range (https://www.usb.org/usb-charger-pd) which adds "three new fixed voltages: 28V (above 100W), 36V (above 140W) and 48V (above 180W)" for charging bigger devices like laptops or electric scooters. Plus a "new adjustable voltage mode enabling a range from 15V to one of three maximum voltages (28V, 36V, or 48V) depending on the available power allowing the device being powered to request specific voltages to a 100 mV resolution." That first quote is pretty clear: we now just have bigger voltages available so we can keep under the 5A current limit that fixes how much current the contacts themselves can handle with standard USB C ports/cables. The second is interesting because it implies we can now select voltages that are outside the standard issue. Now AVS only allows adjustment over 15V, probably this was a compromise since there's big jumps between 28/36/48V. There's also a separate variable-voltage specification called Programmable Power Supply (https://hackaday.com/2025/03/24/pps-is-the-hottest-usb-c-feature-you-didnt-know-about/) a.k.a PPS a.ka. "Fast Charge" (https://www.usb.org/node/585) which allows finer resolution from 3.3V up to 21V - or whatever is the max voltage on the power adapter - in 20mV voltage steps and 50mA current steps. Popularized by tablet/phone maker Samsung but now is appearing on other devices, it recognizes that often times charging speed is limited by the thermal dissipation capabilities of the charging circuitry. That is to say, even with buck converters, if they use tiny SMT parts there's still an 'optimal' voltage and current level that will give the best efficiency and thus charge rate. Just like not all voltages are always supported by USB PD power supplies, PPS support is not required so check the side of the adapter or the manual, to see if it mentions PPS and the voltage/current range. For PPS support, you need to use the AP33772S (https://www.digikey.com/short/59d9mbvm) because there's fine tuning required. But if you just want 'every day' AVS/PD support, where you can select the voltage and current required, the AP33771C (https://www.digikey.com/short/022nd0fp) is much simpler. Instead of having a full I2C setup and configuration, two resistors are queried on power up and used to auto-negotiate. The onboard LED can provide some basic feedback on whether negotiation succeeded. According to the AP33772S datasheet, there is a variant of the chip, AP33772SDKZ-13-FA02 (https://www.digikey.com/en/products/detail/diodes-incorporated/AP33772SDKZ-13-FA02/27346457) that supports having VSEL resistor for initial voltage configuration - that part is available for special order only. If you want a simple, low-cost way to add USB Type C power delivery with extended voltage support and PPS capabilities, the the AP33772S (https://www.digikey.com/short/59d9mbvm) and AP33771C (https://www.digikey.com/short/022nd0fp) are easy ways to make customizable or stand-alone power supplies easy. Now there's no excuse to not convert your next design to run on USB and ditch that confusing DC power plug for good! Whichever one you choose, they're both in stock right now at DigiKey for immediate shipment. There's even eval boards (https://www.digikey.com/en/product-highlight/d/diodes/ap3377-usb-sink-controllers) to get your design kick-started fast. Order today and you'll have fresh chips in hand by tomorrow to make your power delivery dreams come true.

This week we got a request on the forums (https://forums.adafruit.com/viewtopic.php?t=219635) for a way to read PT100/PT1000 RTD sensors over I2C. To be honest, we only really stock the MAX31865 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX31865ATP/3681476) which is SPI only. Let's find a chip that could do RTD reads over I2C: that would require 24-bit precision, but not necessarily high speed! Also ideally it could do differential reads. See the chosen part on DigiKey https://www.digikey.com/short/q7z2575h #circuitpython #sensorhacks #thegreatsearch

This week we got Claude working natively on Windows (yay!) which speeds up development since we're not hitting the filesystem through multiple layers. That meant we also worked on a bunch of little breakouts: the BMP585 protos came in and those worked fine. Plus we knocked out the VEML6046 RGB+IR sensor library (https://github.com/adafruit/Adafruit_VEML6046) and started work on a few others. It turns out the bq25628e (https://github.com/adafruit/Adafruit_bq25628e) was not what we wanted in a charger, because ILimit doesn't affect the charge rate, which is like 40mA by default - boo! We'll find another alternative and also try to get back to that bq25798 (https://github.com/adafruit/Adafruit_bq25798) solar charger shortly. We also worked on the e-Ink bonnet, which worked great as rev A and only needed some pinout swaps - thanks to BlitzCity for updating the CircuitPython-api EPD library (https://github.com/adafruit/Adafruit_CircuitPython_EPD) to add support for the bigger 7.5" & friends which we verified on Raspberry Pi and also the Particle Tachyon - speaking of which we are getting Blinka support into main for that board! (https://github.com/adafruit/Adafruit_Blinka/pull/1001) And on The Great Search - 24-bit I2C ADC Chip for RTD sensors #circuitpython #sensorhacks #thegreatsearch

we prototype an e ink bonnet for raspberry pi and friends, drive displays over spi and i2c, and try a particle tachyon board to push cellular updates with zero wires. image dithering tests, a local solar powered llm that turns daily news into art so you can glance instead of doomscroll, and early ideas for portable e ink graffiti boxes. spi and i2c bring-up, dithering workflow, cellular update loop, and next steps to get the board into the shop. @particle #tachyon @Qualcomm #dragonwing #eink #opensource Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week on EYE ON NPI we're featuring some open source hardware from one of our favorite hardware manufacturers! It's the Arduino Nano R4 System on Module (https://www.digikey.com/en/product-highlight/a/arduino/nano-r4) a miniaturized version of the Arduino UNO R4 and Minima (https://blog.adafruit.com/2023/07/27/eye-on-npi-arduino-uno-r4-minima-and-uno-r4-wifi-boards-digikey-arduino-digikey-adafruit/) versions we covered on EYE ON NPI about two years ago! taking a cue from popular 'castellated single side' PCB proto boards on the market, the Nano comes in two options, one with headers (https://www.digikey.com/en/products/detail/arduino/ABX00143/26766495) for easy installation into existing Arduino Nano expansion kits or breadboards, and one with reflowable castellations (https://www.digikey.com/en/products/detail/arduino/ABX00142/26766490) The Arduino Nano (https://www.digikey.com/en/products/detail/arduino/A000005/2638989) is second only to the UNO as the definitive Arduino board that 'everyone got started with'. Many folks would start with the chunky UNO and then migrate to the Nano to get something that plugs into a breadboard for compact assembly. With a USB connector on one end, button and LEDs and programming header on the top, this board powered tens of thousands of builds. So it's not surprising that Arduino iterated on this design with a wide variety of chips like the RP2040 (https://www.digikey.com/en/products/detail/arduino/ABX00052/14123941) and ESP32 (https://www.digikey.com/en/products/detail/arduino/ABX00092/21219771) The latest generation is the Renesas RA4M1 series - which updates the original ATmega328 8-bit microcontroller to a beefy Cortex M4 with FPU. You get 48MHz clock, 256KB of Flash, 32KB of SRAM, ADC, DAC, CAN, captouch and other extras. The FPU in particular makes it a nice upgrade to the cortex M0/M0+. The best part is that with the 5V logic support of the R7FA4M1AB3CFM (https://www.digikey.com/en/products/detail/renesas-electronics-corporation/R7FA4M1AB3CFM-AA0/10447195), it makes for a great drop-in replacement when a 3V logic chip like the RP2040/ESP32 won't work as well. Plus you get lots of nice linear ADCs, the RP2040 only has 4 and the ESP32's are non-linear and sometimes don't work when WiFi is active. We also love that they added a Qwiic (https://www.sparkfun.com/qwiic) connector on the end! We use this for all our Stemma QT sensors, and between the many companies that have joined in the ecosystem there are easily a thousand different ons/displays/accessories that can plug in directly for instant expansion. If you want to get the latest Nano from the manufacturer of genuine Arduino boards, DigiKey is a authentic distributor and has tons of the Arduino Nano R4 (https://www.digikey.com/short/3brjrnjp) in stock right now for (https://www.digikey.com/en/products/detail/arduino/ASX00061/26744081) immediate shipment! Pick from the castellated flat or soldered-header variety, and don't forget to also grab some Arduino Nano accessories to get your design prototyped fast. Order today and your Nano will fly out of the DigiKey warehouse and arrive at your doorstep by tomorrow morning.
