The Micro:bit V2.0 is a pocket-sized computer that you can code, customise and control to bring your digital ideas, games and apps to life. Each element is completely programmable via easy-to-use software on a dedicated website (www.microbit.co.uk) that can be accessed from a PC, tablet, or mobile.


Board overview 2.0.

There are two programmable buttons that can be used to control games or pause and skip songs on a playlist. The BBC micro:bit can even detect motion and tell you which direction you are heading in. Build-in Low Energy Bluetooth connectivity enables the BBC micro:bit to interact with other devices and the internet.


BBC micro:bit is a BBC initiative to get young people in the UK coding. A royalty from the sale of this BBC micro:bit merchandise helps promote digital creativity amongst young people in the UK.




The nRF52 application processor is where user programs run. A single, complete application including user code, runtime code and Bluetooth stack is loaded and run directly from on-chip flash memory. All user accessible GPIO pins are provided by this processor. There is an on-board 2.4GHz radio peripheral used to provide Bluetooth and custom radio capabilities via an off-chip aerial.

The on-board 2.4GHz transceiver supports a number of other radio communications standards, on which we build the microbit-radio protocol This protocol provides a very simple small-packet broadcast radio interface between other devices that support it, such as other micro:bit devices. The ‘radio’ interface that appears in a number of the languages on the micro:bit is built on top of this protocol. Additionally, the micro:bit runtime software adds a ‘group code’ to each data payload, allowing for simple user managed device addressing and filtering to take place.

The two buttons on the front of the micro:bit, and the one button on the back, are tact momentary push-to-make buttons. The back button is connected to the KL27 interface processor and to the NRF52 processor for system reset purposes. This means that the application will reset regardless of if it is powered from USB or from battery.

Front buttons A and B can be programmed in the user application for any purpose. A and B are debounced by software, which also includes short press, long press, and ‘both A+B’ press detection. Buttons operate in a typical inverted electrical mode, where a pull-up resistor ensures a logical ‘1’ when the button is released, and a logical ‘0’ when the button is pressed. Both A and B buttons are connected to GPIO pins that are also accessible on the micro:bit edge connector.

Debounce (A & B) software debounced, 54ms period
Pullup (A & B) external 4K7, (System) 10K


The display is a 5×5 array of LEDs. It is connected to the micro:bit as a 5×5 matrix. Runtime software repeatedly refreshes this matrix at a high speed, such that it is within the user persistence of vision range, and no flicker is detected. This LED matrix is also used to sense ambient light, by repeatedly switching some of the LED drive pins into inputs and sampling the voltage decay time, which is roughly proportional to ambient light levels.

Physical structure 5×5 matrix
Electrical structure 5×5
Intensity control Software controlled up to 255 steps

The micro:bit has a combined accelerometer and magnetometer chip that provides 3-axis sensing and magnetic field strength sensing. It also includes some on-board gesture detection (such as fall detection) in hardware, and additional gesture sensing (e.g. logo-up, logo-down, shake) via software algorithms. A software algorithm in the standard runtime uses the on-board accelerometer to turn readings into a board orientation independent compass reading. The compass must be calibrated before use, and the calibration process is automatically initiated by the runtime software. This device is connected to the application processor via the I2C bus.

The micro:bit has a footprint for two different motion sensors: one made by ST (the LSM303AGR) and one by NXP (FXOS8700CQ). The micro:bit DAL supports both of these sensors, detecting them at runtime. Only one sensor will ever be placed.

Features 3 magnetic field and 3 acceleration axes , 2/4/8/16g ranges
Resolution 8/10/12 bits
