.. zephyr:board:: maix_m0s_dock

Overview

The M0S is a very small module measuring 10x11mm using the BL616 SoC as the main control chip, with the following features:

• Tri-Mode Wireless: WiFi6 / BT 5.2 / Zigbee
• High Frequency：320MHz default
• Ultra-low Power Consumption：Wifi6 low power consumption feature
• High speed USB：Support USB2.0 HS OTG，up to 480Mbps
• Rich peripheral ports：Support RGB LCD，DVP Camera，Ethernet RMII and SDIO
• Tiny Size：Place ceramic antenna on 10x11 mm tiny size, and route all IO out

The M0S Dock is a carrier board for the M0S module and pushes out some of its I/O pins.

Supported Features

.. zephyr:board-supported-hw::

System Clock

The M0S (BL616) Dock Board is configured to run at maximum speed (320MHz) and can be overclocked to 480 MHz.

Serial Port

The maix_m0s_dock board uses UART0 as default serial port. It is connected to the pins on the side of the USB port.

Programming and Debugging

Samples

#. Build the Zephyr kernel and the :zephyr:code-sample:hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: maix_m0s_dock :goals: build flash

#. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:/dev/ttyUSB0. For example:

.. code-block:: console

  $ screen /dev/ttyUSB0 115200

Connection should be configured as follows:

  - Speed: 115200
  - Data: 8 bits
  - Parity: None
  - Stop bits: 1

Then, unpower and re-power the board.

.. code-block:: console

  *** Booting Zephyr OS build v4.2.0 ***
  Hello World! maix_m0s_dock/bl616c50q2i

Congratulations, you have maix_m0s_dock configured and running Zephyr.
