UG446: xGM210PB22 Wireless Gecko
Module Radio Board User's Guide
A Wireless Starter Kit with the BRD4308D Radio Board is an ex-
cellent starting point to get familiar with the xGM210PB22 Wireless
Gecko Module. It also provides the necessary tools for developing
a Silicon Labs wireless application.
BRD4308D contains the xGM210PB22 Module and is a plug-in board for the Wireless
Starter Kit Mainboard.
The Wireless Starter Kit Mainboard contains an on-board J-Link debugger with a Packet
Trace Interface and a virtual COM port, enabling application development and debugging
the attached radio board as well as external hardware. The mainboard also contains
sensors and peripherals for easy demonstration of some of the xGM210P's many capa-
bilities.
This document describes how to use the BRD4308D Radio Board together with a Wire-
less Starter Kit Mainboard.
