CAN bus pin access and extra hardware

Official Hardware Portenta Family Portenta H7
1

For the Portenta H7 family, what additional hardware (if any) is required to use CAN-FD over a wired connection? My application is space constrained so I'd probably end up making my own breakout board. I'm not sure if I would need to include a transceiver or if the H7 already has one.

Thanks

I am not familiar with the part but the odds are extremely nil that it has the buss driver on chip because of the buss driving/receiving electrical requirements. The data sheet should be clear on that.

Hi everyone!

An external transceiver is needed. You can use the Portenta Hat Carrier or Portenta Mid Carrier, which have compact sizing and both incorporate a high-speed CAN FD transceiver.
More information on CAN bus implementation is available on Arduino Docs:

Best,
