Get creative, get connected & get coding with the latest BBC Micro:bit Board. Not only does the new V2 board sense and react sound (with the built-in microphone) but you can also play around with sound via the built-in speaker. All the existing features in the V1 micro:bit board are still in the V2 model.

Micro:bit by BBC has become the heart of countless creative digital technology projects around the world and a trusted educational learning system. This tiny programmable platform teaches through invention. Learn to code, design animated LED games, interface with sensors, all on the one board. Micro:bit users have full access to the BBC micro:bit website where fresh lesson plans are shared along with tutorials and tips for everyone be you educators, parents, workshop coordinators or just an aspiring maker.

The Micro:bit is easy to code with, all you need is your web browser and a micro USB cable and you are ready to start all kinds of exciting STEM/STEAM experiments, no need for any extra software to be installed.
Micro:bit has also developed a mobile app for coding over Bluetooth (without a USB cable), that makes it even easier to get everyone coding with hardware.

Please Note: The colour within the micro:bit pictured may not match the colour of the micro:bit you receive as the shipments contain mixed colours. A colour preference unfortunately cannot be chosen. Pictures show V2.00 board, however current stock is V2.21. This is due to a minor chipset change. You can read more about the change here
