Desk of Ladyada - Prototyping CAN FD Featherwing & BFFs

Adafruit Industries

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
