4.4 Simplicity Connector
Note:
The Wireless Starter Kit Mainboard does not support this feature when used together with the Wizard Gecko WGM110 Module.
The Simplicity Connector featured on the Wireless Starter Kit Mainboard allows the Virtual COM port interface to be used towards an
external target. The pinout is illustrated in the figure below.
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.

Figure 4.5 Simplicity Connector
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 BRD4320A Radio Board from the WSTK Mainboard to avoid
having the Radio Board current consumption added to the measurements.
