1. Introduction

The EFR32xG21 Wireless Gecko Wireless SoC is featured on a radio board that plugs directly into a Wireless Starter Kit (WSTK) Main-
board. The mainboard features several tools for easy evaluation and development of wireless applications. An on-board J-Link debug-
ger enables programming and debugging on the target device over USB or Ethernet. The Advanced Energy Monitor (AEM) offers real-
time current and voltage monitoring. A virtual COM port interface (VCOM) provides an easy-to-use serial port connection over USB or
Ethernet. The Packet Trace Interface (PTI) offers invaluable debug information about transmitted and received packets in wireless links.
All debug functionality, including AEM, VCOM, and PTI, can also be used towards external target hardware instead of the attached ra-
dio board.
A 20-pin expansion header (EXP header) is also provided that allows connection of expansion boards (EXP boards) to the kit.

1.1 Radio Boards

A Wireless Starter Kit consists of one or more mainboards and radio boards that plug into the mainboard. Different radio boards are
available, each featuring different Silicon Labs devices with different operating frequency bands.
Since the mainboard is designed to work with all different radio boards, the actual pin mapping from a device pin to a mainboard feature
is done on the radio board. This means that each radio board has its own pin mapping to the Wireless Starter Kit features, such as
buttons, LEDs, the display, the EXP header and the breakout pads. Because this pin mapping is different for every radio board, it is
important that the correct document be consulted which shows the kit features in context of the radio board plugged in.
This document explains how to use the Wireless Starter Kit when the EFR32xG21 2.4 GHz 10 dBm with EFP Radio Board (BRD4179B)
is combined with a Wireless STK Mainboard. The combination of these two boards is hereby referred to as a Wireless Starter Kit (Wire-
less STK).

1.2 Ordering Information

BRD4179B can be obtained as a separate radio board, SLWRB4179B. The radio board is intended to be used together with a Wireless
STK Mainboard (BRD4001A) which must be obtained separately.
