UG476: Z-Wave 700 - EFR32ZG14 Long
Range Wireless Starter Kit User's Guide
A Wireless Starter Kit with the BRD4206A Radio Board is an ex-
cellent starting point to get familiar with the EFR32 Wireless
Gecko Z-Wave® Wireless System-on-Chip. It also provides the
necessary tools for developing a Silicon Labs Z-Wave gateway ap-
plication.
BRD4206A is a plug-in board for the Wireless Starter Kit Mainboard, and it is a complete
reference design for the EFR32ZG14 Wireless SoC. The board features an SMA con-
nector for RF connection and an optional 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 EFR32's many capabili-
ties.
This document describes how to use the BRD4206A Radio Board together with a Wire-
less Starter Kit Mainboard.
