Current Measurement Header

The WLR089 Xplained Pro Evaluation board provides a right-angled 1x2, 100-mil pin header (J103) for the MCU current measurement. Powering the WLR089U0 module 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.

Warning: Removing the jumper from the pin header while the kit is powered on may cause the WLR089U0 module to be powered through its I/O pins. This may cause permanent damage to the device.
