This PiCANFD board with LIN-bus.Classic CAN and CAN FD is provided by the Microchip MCP2518FD IC.
LIN-bus is provided by a dsPIC33 micro-controller. Communication to the Pi is over 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 running in GUI mode.Easy to install SocketCAN driver. Programming can be done in C or Python.Optional 3A SMPS module which can power the PiCAN FD LIN-bus board and Raspberry Pi from 7 to 24v external supply.
