3.3 Breakout Pads

Most pins of the EZR32 are routed from the radio board to breakout pads at the top and bottom edges of the Wireless STK 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 EZR32
maps to the pin numbers printed on the breakout pads. To see the available functions on each, please refer to the data sheet for
