BRD4308D Reference Manual

The BRD4308D Wireless Gecko Radio Board contains a Wireless Gecko module, which
integrates Silicon Labs' EFR32MG22 Wireless Gecko SoC into a small form factor mod­ule. The fully certified module contains all components (a high-performance transceiver,
an energy efficient 32-bit MCU, crystals, RF passives, and antenna) required for a sys-

tem-level implementation of Zigbee®, Thread® Bluetooth® and multi-protocol (ZigBee +
Bluetooth) networks operating in the 2.4 GHz band with 10 dBm output power.

The BRD4308D Wireless Gecko Radio Board plugs into the Wireless Starter Kit Main­board, which is included with the Wireless Gecko Starter Kit and gives access to dis­play, buttons, and additional features from expansion boards. With the supporting Sim­plicity Studio suite of tools, developers can take advantage of graphical wireless appli­cation development, mesh networking debug and packet trace, and visual energy profil­ing and optimization.

This document contains a brief introduction and description of the BRD4308D Radio
Board features, focusing on the RF performance.

Introduction

1. Introduction

The BRD4308D Radio Boards provide a development platform (together with the Wireless Starter Kit Mainboard) for the Silicon Labs
Wireless Gecko modules.

By carrying the MGM210PB22 module, the BRD4308D Radio Board is designed to operate in the 2400-2483.5 MHz with the maximum
of 10 dBm output power.

To develop and/or evaluate the MGM210PB22 module, the BRD4308D Radio Board can be connected to the Wireless Starter Kit Main­board to get access to display, buttons, and additional features from expansion boards (EXP boards).
