Better to have a microcontroller with built in CAN controller directly accessible from memory. You must add a transceiver to each microcontroller to use it's CAN functionality. I developed FlexCAN_T4 with performance in mind, and functions not available on any other open source library out there, and is being used in vehicles as well as communications link between mcus using a protocol I wrote for CAN and CANFD.
I haven't found a ready solution, so you will likely have to create it yourself ifyou want it as a shield/cape (pleasase prove me wrong if a ready board exists).

It has 3 CAN bus support, I use 2 in my car. You only feed it 12v and CAN lines, thats it, then use USB cable to debug or program
