    Does anyone know how to connect this canbus module to teensy 3.2? https://www.longan-labs.cc/1030001.html
    Connect to can pins ? Or serial 1?

    That CAN bus module has to be connected to Teensy 3.2 serial pins [pins 0 & 1].
    You are aware that a Teensy 3.2 already has a CAN bus controller built-in? And that you only need to connect a cheap CAN bus transceiver module?
    See this thread for more info.

    No, you do have to use a CAN transceiver for a Teensy 3.2. You don't need to have a separate CAN controller because that controller is built into a Teensy 3.2.
