Cool! I've wanted to try using Rust with a Teensy Micromod but right now the CAN drivers don't actually support the third CAN bus nor will they do CAN-FD like the third bus can do. I was going to try to help with that but I never got enough time...
I'm developing a rugged CAN FD transceiver module, and I'm curious whether anyone else would want one.
I'm trying something different: a dev board that's production-ready, with proper line protection built in, breadboard-friendly, and on...
