4. Connectors

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

4.1 Breakout Pads

Most of the EFR32'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 EFR32 maps to the pin numbers printed on the breakout pads. To see the available functions on each, please refer to the
EFR32MG1P233F256GM48 Data Sheet.
