UG433: BGM220S Wireless Gecko Module
Starter Kit User's Guide
A Wireless Starter Kit with the BRD4310A Radio Board is an ex-
cellent starting point to get familiar with the BGM220S Wireless
Gecko SiP Module. It also provides the necessary tools for devel-
oping a Silicon Labs wireless application.
BRD4310A contains the BGM220S Module, and it 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 BGM220S's many capa-
bilities.
This document describes how to use the BRD4310A Radio Board together with a Wire-
less Starter Kit Mainboard.
