UG349: MGM13S12 Blue Gecko Module
Radio Board User's Guide
A Wireless Starter Kit with the BRD4305E Radio Board is an ex-
cellent starting point to get familiar with the MGM13S Mighty
Gecko SiP Module. It also provides the necessary tools for devel-
oping a Silicon Labs wireless application.
BRD4305E contains the MGM13S12 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 MGM13S's many capa-
bilities.
This document describes how to use the BRD4305E Radio Board together with a Wire-
less Starter Kit Mainboard.
