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.
