4.4 Simplicity Connector
The Simplicity Connector featured on the Wireless Starter Kit Mainboard enables 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. To
monitor the current consumption of an external target with the AEM, unplug the WSTK Radio Board from the WSTK Mainboard to avoid
that the Radio Board current consumption is added to the measurements.
