1. Introduction
The EFR32xG24 Wireless Gecko Wireless SoC is featured on a radio board that plugs directly into a Wireless Starter Kit (Wireless
STK) Mainboard or a Wireless Pro Kit Mainboard. The mainboards feature several tools for easy evaluation and development of wire-
less applications. An on-board J-Link debugger 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 radio board.
To further enhance its usability, the mainboard contains sensors and peripherals that demonstrate some of the many capabilities of the
EFR32xG24. The mainboard also has a 20-pin EXP header which can be used for connecting EXP boards to the kit or for easy connec-
tion to I/Os on the radio board target IC.
1.1 Radio Boards
A Wireless Pro Kit consists of one or more mainboards and radio boards that plug into the mainboard. Different radio boards are availa-
ble, each featuring different Silicon Labs devices with different operating frequency bands. Because the mainboards are designed to
work with 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 Pro 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 to consult the correct docu-
ment, which shows the kit features in context of the radio board plugged in.
1.2 Mainboards
The EFR32xG24 2.4 GHz 10 dBm Radio Board (BRD4186C) can be used with either a Wireless Starter Kit Mainboard (BRD4001A) or
a Wireless Pro Kit Mainboard (BRD4002A). The Wireless Pro Kit Mainboard is the successor to the Wireless Starter Kit Mainboard,
which comes with some improvements and added features including increased AEM measurement range and sample rate, variable
VMCU voltage, joystick, and a Mini Simplicity Connector. Kit features, such as the Si7021 sensor and the EXP header, are available on
the same EFR32xG24 pins regardless of the mainboard being used, but the pinout to the breakout pads differs. The combination of the
EFR32xG24 2.4 GHz 10 dBm Radio Board with either one of these mainboards is hereby referred to as a Wireless Pro Kit as the figure
below illustrates.

Note:
This document explains how to use the Wireless Pro Kit when the EFR32xG24 2.4 GHz 10 dBm Radio Board (BRD4186C) is
combined with either a Wireless Starter Kit Mainboard (BRD4001A) or a Wireless Pro Kit Mainboard (BRD4002A). Since some of the
functionality of the kit depends on the type of mainboard used, it is important to consult the right information in the user guide whenever
there are discrepancies.
