Overview
The EFR32BG13 Blue Gecko Bluetooth® Low Energy Radio Board is one of the two
radio boards delivered with SLWSTK6020B Bluetooth SoC Starter Kit_. It
contains a Wireless System-On-Chip from the EFR32BG13 family built on an
ARM Cortex®-M4F processor with excellent low power capabilities.
The BRD4104A a.k.a. SLWRB4104A radio board plugs into the Wireless Starter Kit
Mainboard BRD4001A and is supported as one of :ref:silabs_radio_boards.

The EFR32BG13P SoC is configured to use the 38.4 MHz external oscillator on the board.
The EFR32BG13P SoC has three USARTs and one Low Energy UARTs (LEUART). USART0 is connected to the board controller and is used for the console.
Programming and Debugging
.. zephyr:board-supported-runners::
Connect the BRD4001A board with a mounted BRD4104A radio module to your host computer using the USB port.
Here is an example for the :zephyr:code-sample:hello_world application.
.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: slwrb4104a :goals: flash
Open a serial terminal (minicom, putty, etc.) with the following settings:
Reset the board and you should see the following message in the terminal:
.. code-block:: console
Hello World! slwrb4161a
