4.3.3 Current Measurement Header

A right-angled 1x2, 100 mil pin header marked with the MCU current measurement is located at the upper edge of the SAM R34 Xplained Pro. All power to the SAM R34 is exclusively routed through this header (excluding power to extension 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 SAM R34 to be powered through its I/O pins. This may cause permanent damage to the device.
