Hey there,

Teensy 4.1 comes equipped with 3 CAN-BUS ports. Your MM only references 1 CAN-BUS, but the required pins for all 3 CANs are present (M11, G11, M13, H13, E4, C3). Do you foresee any issues in utilizing all 3 CANBUS ports simultaneously?

Thanks,
Tal

As long as you don't need those pins for something else it should be fine https://learn.sparkfun.com/tutorials/mi ... e-overview

Note that *sending* CAN messages requires a CAN transceiver, reading is good-to-go

I use all three CAN buses on this micromod board. Tony's normal FlexCAN_T4 library works fine out of the box. Just make sure you put your transceivers on the pins it expects them on.
