UG373: ZGM130S Zen Gecko
Wireless Starter Kit User's Guide
A Wireless Starter Kit with the BRD4200A Radio Board is an ex-
cellent starting point to get familiar with the ZGM130S Zen Gecko
Z-Wave® SiP Module. It also provides the necessary tools for de-
veloping a Silicon Labs wireless application.
BRD4200A is a plug-in board for the Wireless Starter Kit Mainboard. It is a complete ref-
erence design for the ZGM130S SiP Module. The board features an SMA connector for
RF connection, or a PCB antenna that can be selected by moving a 0 Ω resistor.
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 ZGM130S's many capa-
bilities.
This document describes how to use the BRD4200A Radio Board together with a Wire-
less Starter Kit Mainboard.
