The power header can be used to connect external power to the SAM E54 Xplained Pro kit. The kit
automatically detects and switches to any external power if supplied. The power header can also be used
to supply power to external peripherals or extension boards. Ensure that the total current does not
exceed the recommended current limit of the on-board regulator when using the 3.3V pin.
