1. Introduction
The BGM220S Wireless Gecko Module is featured on a radio board that plugs directly into a Wireless Starter Kit (WSTK) Mainboard.
The mainboard features several tools for easy evaluation and development of wireless applications. An on-board J-Link debugger ena-
bles 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 Ether-
net. 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 demonstrates some of the many capabilities of
the BGM220S. 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 BGM220S Wireless Gecko Module Radio Board (BRD4310A) 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
BRD4310A can be obtained as part of SLWSTK6103A Wireless Gecko Module Starter Kit or as a separate radio board, SLWRB4310A.

Figure 3.1. Mainboard Connector Layout
3.1 J-Link USB Connector
The J-Link USB connector is situated on the left side of the Wireless Starter Kit Mainboard. Most of the kit's development features are
supported through this USB interface when connected to a host computer, including:
• Debugging and programming of the target device using the on-board J-Link debugger
• Communication with the target device over the virtual COM port using USB-CDC
• Accurate current profiling using the AEM
In addition to providing access to development features of the kit, this USB connector is also the main power source for the kit. USB 5V
from this connector powers the board controller and the AEM. It is recommended that the USB host be able to supply at least 500 mA
to this connector, although the actual current required will vary depending on the application.
3.2 Ethernet Connector
The Ethernet connector provides access to all of the Wireless Starter Kit's development features over TCP/IP. The Ethernet interface
provides some additional development features to the user. Supported features include:
• Debugging and programming of the target device using the on-board J-Link debugger
• Communication with the target device over the virtual COM port using TCP/IP socket 4901
• "VUART" communication with the target device over the debug SWD/SWO interface using TCP/IP socket 4900
• Accurate current profiling using the AEM
• Real-time radio packet and network analysis using the Packet Trace Interface
• Access to advanced configuration options using the admin console over TCP/IP socket 4902
Note: The Wireless Starter Kit cannot be powered using the Ethernet connector, so in order to use this interface, the USB connector
must be used to provide power to the board.

3.3 Breakout Pads
Most pins of the BGM220S are routed from the radio board to breakout pads at the top and bottom edges of the Wireless STK Main-
board. A 2.54 mm pitch pin header can be soldered on for easy access to the pins. The figure below shows you how the pins of the
BGM220S map to the pin numbers printed on the breakout pads. To see the available functions on each, refer to the data sheet for
BGM220SC12WGA1.

3.4 EXP Header
The EXP header is an angled 20-pin expansion header provided to allow connection of peripherals or plugin boards to the kit. It is loca-
ted on the right-hand side of the mainboard, and it contains a number of I/O pins that can be used with most of the BGM220S Wireless
Gecko's features. Additionally, the VMCU, 3V3, and 5V power rails are also exported.
The connector follows a standard which ensures that commonly used peripherals, such as an SPI, a UART, and an I2C bus, are availa-
ble on fixed locations in the connector. The rest of the pins are used for general purpose IO. This allows the definition of expansion
boards (EXP boards) that can plug into a number of different Silicon Labs Starter Kits.
The figure below shows the pin assignment of the EXP header. Because of limitations in the number of available GPIO pins, some of
the EXP header pins are shared with kit features.

3.4.1 EXP Header Pinout
The pin-routing on the BGM220S is very flexible, so most peripherals can be routed to any pin. However, many pins are shared be-
tween the EXP header and other functions on the Wireless STK Mainboard. The table below includes an overview of the mainboard
features that share pins with the EXP header.
