3.6 Simplicity Connector
The Simplicity Connector enables the advanced debugging features, such as the AEM, the virtual COM port, and the Packet Trace
Interface, to be used towards an external target. The pinout is illustrated in the figure below.

Note: Current drawn from the VMCU voltage pin is included in the AEM measurements, while the 3V3 and 5V voltage pins are not.
When monitoring the current consumption of an external target with the AEM, unplug the radio board from the Wireless STK Mainboard
to avoid adding the radio board current consumption to the measurements.
