Current Measurement Header

An angled 1x2, 100mil pin-header marked with MCU current measurement is located at the upper edge of the SAM L21 Xplained Pro. All power to the ATSAML21J18B is routed through this header. To measure the power consumption of the device remove the jumper and replace it with an ammeter.

CAUTION: Removing the jumper from the pin-header while the kit is powered may cause the ATSAML21J18B to be powered through its I/O pins. This may cause permanent damage to the device.
