    CAN transceiver PCB for Teensy 3.6

    I will like to connect a CAN Transceiver PCB using the Microchip MCP2551 (or reasonable equivalent) to a Teensy 3.6 in a breadboard just using jumpers. No soldering.

    Looking for recommendations on a COTS (Commercial Off-the-shelf) CAN Transceiver PCB's to accomplish this.

    I've not used the CAN work, but I recall seeing these adapters for 1/2 CAN channels on the 3.5/3.6 go by on tindie.com:


    Note, these boards have SN65HVD230D transceivers already installed.

    I use those. They are cheap, and they are ultra-reliable.. Also, they are 3.3V not 5V. I didn't use the MCP2xxx because it has to be addressed with SPI (I believe) as it is a MCU and not just a transceiver. Using FlexCAN and a Teensy 3.5 (or 3.6), I can reliably and without fault, use all the hardware DMA buffers on the teensy.

    For multi-node BUS, you will need to desolder the 120Ohm resistor between CAN-H and CAN-L on the SN65HVD230 (Pins 5 and 6). Only the "Beginning" and the "End" of the BUS need the resistors.
