4.2.2 Power Header

The four pin power header on the PROTO1 Xplained Pro extension board is used to probe the voltage on the board. The pins of the header are marked in silk screen with VCC for target voltage and GND for ground.

CAUTION:

The two pin power header should not be used to apply power to the PROTO1 Xplained Pro. The board will get power from the Xplained Pro MCU board through the 20-pin extension connector.
