EFR32 BRD4187C (xG24-RB4187C)
#############################
Overview
********
The EFR32MG24 Mighty Gecko Radio Board is one of the two
radio boards delivered with `xG24-PK6010A Website`_. It contains
a Wireless System-On-Chip from the EFR32MG24 family built on an
ARM Cortex®-M33F processor with excellent low power capabilities.

System Clock
============
The EFR32MG24 SoC is configured to use the 39 MHz external oscillator on the
board.
Serial Port
===========
The EFR32MG24 SoC has one USART and two EUSARTs.
USART0 is connected to the board controller and is used for the console.
Programming and Debugging
*************************
Please refer to
:ref:`Programming and Debugging EFR32 Radio Board <efr32_radio_programming>`
for details on the supported debug interfaces.
Flashing
========
Connect the BRD4002A board with a mounted BRD4187C radio module to your host
computer using the USB port.
Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: efr32_radio_brd4187c
:goals: flash
Open a serial terminal (minicom, putty, etc.) with the following settings:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
Reset the board and you should see the following message in the terminal:
