2.5.3 Xplained Pro Power Header
The power header can be used to connect external power to the Xplained Pro kit. The kit will automatically detect and switch to any external power if supplied. The power header can also be used as supply for external peripherals or extension boards. Care must be taken not to exceed the total current limitation of the on-board regulator when using the target voltage pin.
