The PIC32 WFI32E Curiosity Board can be powered using any of the following sources:
External 5V (J201)
PKOB3 micro-B USB (J302)
Target VBUS micro-B (J204)
Note: For the jumper connections, refer to the PIC32 WFI32E Curiosity Board User’s Guide (DS50003028).
The following table lists the power supply source details and its jumper positions.

Power Input
Description
Jumper Position (J202(1))
External 5V (J201(1))
Connect the Curiosity board to an external 5V power supply.
P/S-VIN (2-1)
PKOB3 micro-B USB (J302(1))
Connect the Type-A male to micro-B USB cable to the USB debug port for power supply.
PKOB-VIN (4-3)
Target VBUS micro-B (J204(1))
Connect the Type-A male to micro-B USB cable to the USB power port for power supply.
VBUS-VIN (6-5)
Note:
For the jumper connections, refer to the PIC32 WFI32E Curiosity Board User's Guide (DS50003028).
The following figure illustrates the jumper positions for powering the Curiosity board. Figure 2-1. Jumper Configuration for Power Input
Note: Ensure that the 3V3_MOD and 3V3_IN of J102 are connected on the WFI32E01PC/WFI32E03PC carrier board.
Use the J202 jumper to select the voltage source for the Curiosity board. The MCP1727 voltage regulator generates a +3.3V power supply for the MCU. Connect the PKOB debugger to a host PC. Turn on the power supply (+3.3V and +5V) to the Curiosity board via a power switch (MIC2005A) to drive the ENABLE signal to high.
