Power Header

The two pin power header on IO1 Xplained Pro can be used together with the GPIO pins to connect external circuitry or probe the voltage on the board. The pins of the header are marked in silk screen with VTG for target voltage and GND for ground.

Info: The two pin power header should not be used to apply power to I/O1 Xplained Pro when connected to an Xplained Pro MCU board as it will get power from the Xplained Pro MCU board through the 20-pin extension connector.
