CAN Pal - CAN Bus Transciever - TJA1051T/3
Product description
If you'd like to connect a board with native CAN Peripheral support, the Adafruit CAN Pal Transceiver will take the 3V logic level signals and convert them to CAN logic levels with the differential signaling required to communicate.
Adafruit has added a few nice extras to this breakout pal to make it useful in many common CAN scenarios.
