SAMC21N Xplained Pro

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 SAMC21N Xplained Pro. All power to the ATSAMC21N18A is exclusively routed through this header (excluding power to headers and peripherals). 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 ATSAMC21N18A to be powered through its I/O pins. This may cause permanent damage to the device.
