PiCAN FD with LIN Bus for Raspberry Pi

This PiCAN FD board comes with a LIN Bus interface, and the Microchip MCP2518FD IC provides classic CAN and CAN FD, while a dsPIC33 micro-controller provides the LIN Bus connection. Communication to the Pi is per UART on ttyS0 using ASCII text commands. Example LIN-bus GUI app is available written in Python3 and tkinter.

The firmware is updatable using the Microchip UnifiedHost java app. This requires the Raspberry Pi to run in GUI mode.

Easy to install SocketCAN driver. Programming is supported in C or Python.
