3.1 Power Supply

The following are the list of sources to power the PIC32 WFI32 Curiosity HPC Board:

  • External supply connector 5V (J201)
  • USB Type-C connector (J206)

The following table lists the power supply source details and its jumper positions.

Table 3-2. Power Supply Sources
Power Input Description Jumper Position (J202)(1)
External supply connector 5V (J201)(2)Connect the PIC32 WFI32 Curiosity HPC Board to an external 5V power supply P/S-VIN (2-1)
USB Type-C™ connector (J206)Connect the Micro-A male to USB Type-C cable to the USB debug port for power supply USB-VIN (4-3)
Note:
  1. Jumper (J202) in Figure 3-3.
  2. The maximum input voltage from the external 5V supply must not exceed 5.5V. Applying a supply voltage higher than 5.5V can damage the board.
The following figure illustrates the jumper positions that power the PIC32 WFI32 Curiosity HPC Board.
