Overview

The Micro Bit (also referred to as BBC Micro Bit, stylized as micro:bit) is an ARM-based embedded system designed by the BBC for use in computer education in the UK.

The board is 4 cm × 5 cm and has an ARM Cortex-M0 processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that are part of the 23-pin edge connector.

More information about the board can be found at the microbit website_.

Flashing

Build and flash applications as usual (see :ref:build_an_application and :ref:application_run for more details).

Here is an example for the :zephyr:code-sample:hello_world application.

First, run your favorite terminal program to listen for output.

.. code-block:: console

$ minicom -D <tty_device> -b 115200

Replace :code:<tty_device> with the port where the board nRF51 DK can be found. For example, under Linux, :code:/dev/ttyACM0.

Then build and flash the application in the usual way.
