6.8. Expansion headers and power distribution

The 3pi+ 2040 control board has several expansion headers (primarily in two areas toward the front of the board) that break out many of the general-purpose I/O lines from the RP2040 microcontroller. Various power inputs, outputs, and control pins are also accessible elsewhere on the board. The following diagrams identify the locations of these pins and the hardware associated with them. These diagrams are also available as a printable PDF:
