4. Connectors

This chapter gives you an overview of the Wireless STK Mainboard connectivity. The placement of the connectors can be seen in the
figure below.

4.1 Breakout Pads

Most of the WGM110's pins are routed from the radio board to breakout pads at the top and bottom edges of the Wireless STK Main-
board. A 2.54 mm pitch pin header can be soldered on for easy access to the pins. The figure below shows you how the pins of the
WGM110 maps to the pin numbers printed on the breakout pads. To see the available functions on each, please refer to the WGM110
Data Sheet.
