Raspberry Pi Pico LIN-bus board

LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. It is a single wire, serial network protocol that supports communications up to 19.2 Kbit/s at a bus length of 40 meters. The need for a cheap serial network arose as the technologies and the facilities implemented in the car grew, while the CAN bus was too expensive to implement for every component in the car. European car manufacturers started using different serial communication technologies, which led to compatibility problems.

This board uses the Raspberry Pi Pico. The Pico has soldered header and the base board is socketed. Different version of the Pico can be plugged in.

Include header version of Pico.

• LIN driver by Microchip MCP2004A.
• Up to 20k baud on LIN
