- All STM32 mcus are rated up to 85°C ambient (there are also parts going up to 125°C). The RP2040 is rated up to 85°C package temp. - STM32 G0/G4/H7 have CAN-FD support. - Only my (unpublished) Klipper fork has CAN-FD support currently. I'm currently using a SB2240 with my Klipper fork.

The fix is quite simple: don't use RP2040 :) There are enough proper MCUs out there with CANFD support. Also using a chip rated to max 85°C on the toolhead is a bad idea. In the meantime I got Klipper working on CANFD @ 4 Mbps. Doing a TEST_RESONANCES the max bus load was around 15% (vs 80%...

Please elaborate such strong claims. IMO it's the other way around. CAN is a very simple protocol and suitable for real-time tasks. It can be used with many different connectors and cables. USB on the other hand is very complex and has strict requirements on connectors and cables. It's not very...
