4.2.6 Current Measurement Header
An angled 1x2, 100mil pin-header marked with MCU current measurement is located at the upper edge of the SAM L22 Xplained Pro. All power to the ATSAML22N18A 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 ATSAML22N18A to be powered through
its I/O pins. This may cause permanent damage to the device.
