This guide is tested with the following boards:
- BigTreeTech Pi v1.2
- U2C Module v1.0
This guide was verified on a BigTreeTech Pi v1.2 running CB1 Debian11 Klipper
This is an instruction to set up a BigTreeTech Pi v1.2 with a U2C Module v1.0 with Klipper. The BigTreeTech Pi v1.2 is a Raspberry Pi alternative with a H616 SoC. The U2C Module v1.0 is a USB-to-CAN adapter, which can be plugged on the top of the BigTreeTech Pi v1.2 as a HAT.
This module is already preconfigured & flashed by BigTreeTech. Turn off the Pi, remove the power supply, and plug the module on the Pi. After the Pi is fully booted again, CAN should be ready.
