      Expansion Plate Explained!

      Here's the Expansion Plate annotated diagram

      Power

      • Standard USB-C UFP port, supports both 12/15V@3A input

      • Provides MPWR_IN to pi-top [4] for 12/15V@3A

      • Power rails from pi-top [4] Modular connector - 5V_USB@1A(USB hub and USB ports), 5V@3A(Servo Motor x4), 3V3@1A(MCU/ICs/misc), VSYS@2.5A(DC motor x4)

      • Motor_VCC is converted by buck-boost convertor from VSYS, so the Motor_VCC rating is about 2A.
