The Adafruit PiCowbell CAN Bus lets you use a Raspberry Pi Pico or Pico W to connect to CAN bus networks for automotive or robotics projects. It has a MCP2515 controller and TJA1051/3 transceiver! The MCP2515 is an extremely popular and well-supported chipset that has drivers in Arduino and CircuitPython and only requires a SPI port and two pins for chip-select and IRQ.
The Adafruit PiCowbell CAN Bus for Pico guide has everything you need to get started with using the Feather. There’s pages for overview, pinouts, CircuitPython, Arduino and resources for download.
