BGM220SC12 Module Radio Board
BRD4310A Reference Manual
The BRD4310A Wireless Gecko Radio Board contains a Wireless Gecko module which
integrates Silicon Labs' EFR32BG22 Wireless Gecko SoC into a small form factor Sys-
tem-in-Package (SiP) module. The fully certified module contains all components (a
high-performance transceiver, an energy efficient 32-bit MCU, HF crystal, RF passives,
and antenna) required for a system-level implementation of Bluetooth
®
Low Energy
wireless networks operating in the 2.4 GHz band with 0 dBm output power.

The BRD4310A Wireless Gecko Radio Board plugs into the Wireless Starter Kit Main-
board, which is included with the Wireless Gecko Starter Kit and gives access to dis-
play, buttons, and additional features from expansion boards. With the supporting Sim-
plicity Studio suite of tools, developers can take advantage of graphical wireless appli-
cation development, BGScript for Python-like scripting, and visual energy profiling and
optimization.
This document contains a brief introduction and description of the BRD4310A Radio
Board features, focusing on the RF performance.
