3.3 Breakout Pads
Most pins of the BGM220P 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
BGM220P map to the pin numbers printed on the breakout pads. To see the available functions on each, refer to the data sheet for
BGM220PC22HNA2.
