+DT-BL10 Development Kit
+#######################
+
+Overview
+********
+
+DT-BL10 Wi-Fi and BLE coexistence Module is a highly integrated single-chip
+low power 802.11n Wireless LAN (WLAN) network controller. It combines an RISC
+CPU, WLAN MAC, a lT1R capable WLAN baseband, RF, and Bluetooth in a single chip.
+It also provides a bunch of configurable GPIO, which are configured as digital
+peripherals for different applications and control usage.
+
+DT-BL10 WiFi Module use BL602 as Wi-Fi and BLE coexistence soc chip. DT-BL10
+WiFi Module integrates internal memories for complete WIFI protocol functions.
+The embedded memory configuration also provides simple application developments.
+
+DT-BL10 WiFi module supports the standard IEEE 802.11 b/g/n/e/i protocol and the
+complete TCP/IP protocol stack. User can use it to add the WiFi function for the
+installed devices, and also can be viewed as a independent network controller.

+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+System Clock
+============
+
+The DT-BL10 board is configured to run at max speed (192MHz).
+
+Serial Port
+===========
+
+The ``dt_bl10_devkit`` board uses UART0 as default serial port. It is connected
+to USB Serial converter and port is used for both program and console.
+
+
+Programming and Debugging
+*************************
+
+.. zephyr:board-supported-runners::
+
+Samples
+=======
+
+#. Build the Zephyr kernel and the :zephyr:code-sample:`hello_world` sample
+application:
+
+   .. zephyr-app-commands::
+      :zephyr-app: samples/hello_world
+      :board: dt_bl10_devkit
+      :goals: build
+
+#. To flash an image using blflash runner:
+
+   #. Press D8 button
+
+   #. Press and release EN button
+
+   #. Release D8 button
+
+   .. code-block:: console
+
+      west flash
+
+#. Run your favorite terminal program to listen for output. Under Linux the
+   terminal should be :code:`/dev/ttyUSB0`. For example:
+
+   .. code-block:: console
+
+      $ minicom -D /dev/ttyUSB0 -o
+
+   The -o option tells minicom not to send the modem initialization
+   string. Connection should be configured as follows:
+
+      - Speed: 115200
+      - Data: 8 bits
+      - Parity: None
+      - Stop bits: 1
+
+   Then, press and release EN button
+
+   .. code-block:: console
+
+      *** Booting Zephyr OS build v4.1.0-4682-g21b20de1eb34 ***
+      Hello World! dt_bl10_devkit/bl602c20q2i
+
+Congratulations, you have ``dt_bl10_devkit`` configured and running Zephyr.
