+Hardware
+********
+
+STM32WB5MMG is an ultra-low-power and small form factor certified 2.4 GHz
+wireless module. It supportsBluetooth |reg| Low Energy 5.4, Zigbee |reg| 3.0,
+OpenThread, dynamic, and static concurrent modes, and 802.15.4proprietary
+protocols. Based on the STMicroelectronics STM32WB55VGY wireless
+microcontroller,STM32WB5MMG provides best-in-class RF performance thanks
+to its high receiver sensitivity and output power signal. Its low-power
+features enable extended battery life, small coin-cell batteries, and
+energy harvesting.

+Supported Features
+==================
+
+The Zephyr STM32WB5MM-DK board configuration supports the following hardware features:
+
++-----------+------------+-------------------------------------+
+| Interface | Controller | Driver/Component                    |
++===========+============+=====================================+
+| UART      | on-chip    | serial port-polling;                |
+|           |            | serial port-interrupt               |
++-----------+------------+-------------------------------------+
+
+
+Other hardware features are not yet supported on this Zephyr port.
+
+The default configuration can be found in the defconfig file:
+``boards/arm/stm32wb5mm_dk/stm32wb5mm_dk_defconfig``
+
+Bluetooth and compatibility with STM32WB Copro Wireless Binaries
+================================================================
+
+To operate bluetooth on STM32WB5MMG, Cortex-M0 core should be flashed with
+a valid STM32WB Coprocessor binaries (either 'Full stack' or 'HCI Layer').
+These binaries are delivered in STM32WB Cube packages, under
+Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/
+For compatibility information with the various versions of these binaries,
+please check `modules/hal/stm32/lib/stm32wb/hci/README`_
+in the hal_stm32 repo.
+Note that since STM32WB Cube package V1.13.2, "full stack" binaries are not compatible
+anymore for a use in Zephyr and only "HCI Only" versions should be used on the M0
+side.
+
+Connections and IOs
+===================
+
+
+Default Zephyr Peripheral Mapping:
+----------------------------------
+
+.. rst-class:: rst-columns
+
+- UART_1 TX/RX : PB7/PB6 ( Connected to ST-Link VCP)
+- LPUART_1 TX/RX : PA3/PA2
+- USB : PA11/PA12
+- SWD : PA13/PA14
+
+System Clock
+------------
+
+STM32WB5MMG System Clock could be driven by internal or external oscillator,
+as well as main PLL clock. By default System clock is driven by HSE clock at 32MHz.
+
+Serial Port
+-----------
+
+STM32WB5MM-DK board has 2 (LP)U(S)ARTs. The Zephyr console output is assigned to USART1.
+Default settings are 115200 8N1.
+
+
+Programming and Debugging
+*************************
+
+Applications for the ``stm32wb5mm_dk`` board configuration can be built the
+usual way (see :ref:`build_an_application`).
+
+Flashing
+========
+
+STM32WB5MM-DK has onboard ST-Link to flash and debug the firmware on the
+module.
+
+
+Flashing `hello_world` application to STM32WB5MM-DK
+----------------------------------------------------
+
+Connect the STM32WB5MM-DK to your host computer using the USB port (CN11).
+Then build and flash an application. Here is an example for the ``hello_world``
+application.
+
+Run a serial host program to connect with your  STM32WB5MM-DK board:
+
+.. code-block:: console
+
+   $ minicom -D /dev/ttyACM0
+
+Then first build and flash the application for the STM32WB5MM-DK board.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: stm32wb5mm_dk
+   :goals: build flash
+
+Reset the board and you should see the following messages on the console:
+
+.. code-block:: console
+
+	Hello World! stm32w5mm_dk
+
+Debugging
+=========
+
+You can debug an application in the usual way.  Here is an example for the
+`Hello_World`_  application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: stm32wb5mm_dk
