The BigTreeTech Pi is an H616 based board based on CB1.
Just in Rpi format board.
It features the same internals as BTT CB1 but adds:
- Fan port
- IR receiver
- ADXL345 Accelerometer connector via SPI
- 24V DC power supply via terminal plugs
- USB to CAN module connector (The actual USB to CAN happens on the external module)
List of currently working things is same as BTT CB1 but also:
- IR receiver
- ADXL345 connector

Changes in V2:
- Add UART alongside aliases and chosen for it
- Add model string
- Enable IR receiver
- Enable SPI0 for ADXL345 connector
Changes in V3:
- Add missing semicolons
- Add pinctrl for SPI0
