Xplained Pro Power Header
The power header can be used to connect external power to the SAM4L8 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 3.3V pin.
