+Connections and IOs
+===================
+
+The EFM32GG12 MCU has six GPIO controllers (PORTA to PORTF), all of which are
+currently enabled for the SLTB009A board.
+
+In the following table, the column **Name** contains pin names. For example, PE1
+means pin number 1 on PORTE, as used in the board's datasheets and manuals.
+

+
+System Clock
+============
+
+The EFM32GG12 MCU is configured to work at 72 MHz.
+
+Serial Port
+===========
+
+The EFM32GG12 SoC has five USARTs, two UARTs and two Low Energy UARTs (LEUART).
+USART0 is connected to the board controller and is used for the console.
+
+Programming and Debugging
+*************************
+
+.. note::
+   Before using the kit the first time, you should update the J-Link firmware
+   from `J-Link-Downloads`_
+
+Flashing
+========
+
+The SLTB009A includes an `J-Link`_ serial and debug adaptor built into the
+board. The adaptor provides:
+
+- A USB connection to the host computer
+- A physical UART connection which is relayed over interface USB serial port.
+
+Flashing an application to SLTB009A
+--------------------------------------
+
+Connect the SLTB009A to your host computer using the USB port.
+
+Here is an example to build and flash the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: efm32gg_stb009a
+   :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'll see the following message on the corresponding serial port
+terminal session:
+
+.. code-block:: console
+
+   Hello World! efm32gg_sltb009a
