Hello,
I just received 2 AVR-CAN boards, and I can’t find documentation on how to wire the two CAN ports together. Does anyone know how to do this, and how they have to be terminated, etc? I only need to connect two boards. Thanks!

I don’t remember exactly but I believe a CAN bus needs somewhere around
a 125 ohm resistor (may be different depending on baud rate) between the
differential signals at each end of the bus, so 2 resistors total.
Is anybody able to do anything with this board? Anything to add?
It looks like this board is not functioning correctly – designed bad and not tested. I have problems with them either. I connected them according to CAN spec and when debugged I saw that boards were always in error mode – BUSOFF error was always appearing when trying to transmitt.
