BigTreeTech U2C v1.x

This is an instruction to set up the BTT U2C with Klipper. There are two possible variants. Use the board as a pure CANBUS adapter (candlelight FW) or a Klipper USB-to-CAN adapter.

This guide is tested with the following boards:

  • BigTreeTech U2C v1.1

This guide was verified on a Pi running MainsailOS

With the U2C, there are few advantages through the Klipper firmware since no freely assignable pins are available on the board.
