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 Starter Kit
Mainboard. 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 map out to the pin numbers printed on the breakout pads. To see the available functions on each, please refer to the
WGM110 Data Sheet.
