Introduction

1. Introduction

The BGM11S Blue Gecko SiP Module itself is featured on a Radio Board that forms a complete reference design, including the RF section and other components.
The Radio Board plugs directly into a Wireless Starter Kit Mainboard. The Mainboard features several tools for easy evaluation and development of wireless 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 demonstrating some of the many capabilities of the BGM11S.

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 BGM11S Blue Gecko SiP Module Radio Board (BRD4303A) is combined with a Wireless STK Mainboard. The combination of these two boards is hereby referred to as a Wireless Starter Kit (Wire­less STK).

1.2 Ordering Information

BRD4303A can be obtained as a separate radio board, SLWRB4303A. The radio board is intended to be used together with a Wireless STK Mainboard that can be obtained with any Silicon Labs Wireless Starter Kit.

3. Connectors

This chapter gives you an overview of the Wireless STK Mainboard connectivity. The placement of the connectors are shown in the figure below.
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
Please note that 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 BGM11S are routed from the radio board to breakout pads at the top and bottom edges of the Wireless STK Main­board. 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 BGM11S maps to the pin numbers printed on the breakout pads. To see the available functions on each, refer to the data sheet for BGM11S22F256GA-V2.

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 loca­ted 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 BGM11S Blue 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 availa­ble 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 BGM11S is very flexible, so most peripherals can be routed to any pin. However, many pins are shared between 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.

3.5 Debug Connector

The debug connector serves multiple purposes based on the "debug mode" setting which can be configured in Simplicity Studio. When the debug mode is set to "Debug IN", the debug connector can be used to connect an external debugger to the BGM11S on the radio board. When set to "Debug OUT", this connector allows the kit to be used as a debugger towards an external target. When set to "De­bug MCU" (default), the connector is isolated from both the on-board debugger and the radio board target device.
Because this connector is electronically switched between the different operating modes, it can only be used when the board controller is powered (i.e. J-Link USB cable connected). If debug access to the target device is required when the board controller is unpowered, connect directly to the appropriate breakout pins.
The pinout of the connector follows that of the standard ARM Cortex Debug+ETM 19-pin connector. The pinout is described in detail below. Even though the connector has support for both JTAG and ETM Trace, it does not necessarily mean that the kit or the on-board target device supports this.
Figure 3.4. Debug Connector
Note: The pinout matches the pinout of an ARM Cortex Debug+ETM connector, but these are not fully compatible as pin 7 is physically
removed from the Cortex Debug+ETM connector. Some cables have a small plug that prevent them from being used when this pin is present. If this is the case, remove the plug, or use a standard 2x10 1.27 mm straight cable instead.
