UG187: BGM113 Blue Gecko Module
Wireless Starter Kit User's Guide
A Wireless Starter Kit with the BRD4301A Radio Board is an ex-
cellent starting point to get familiar with the BGM113 Blue Gecko
Module. It also provides the necessary tools for developing a Sili-
con Labs wireless application.
BRD4301A contains the BGM113 Module, and it is a plug-in board for the Wireless Start-
er 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 BGM113's many capabili-
ties.
This document describes how to use the BRD4301A Radio Board together with a Wire-
less Starter Kit Mainboard.
