The Micro:bit Educational Foundation has announced the manufacturing and launch of the latest version of the micro:bit.

The BBC micro:bit, a pocket-sized computer helping to inspire more than 25 million children to learn digital creativity and computing skills, will receive its first major updates since launching in 2016.

Available from mid-November 2020, it will now include a built-in speaker and microphone, enabling people to learn through sound and to get creative with it straight out-of-the-box. The hardware also includes a number of technical upgrades to ensure that in the future the device is an ideal tool for exploring, understanding and experimenting with AI and ML, as these technologies begin to transform the planet.

The new microbit continues to support all of the same features that teachers and students have come to love, and all the existing lessons and code for the original microbit will be compatible with the new device. In addition, as part of the Micro:bit Educational Foundation’s commitment to keeping the device as cost-effective and accessible as possible, the new device will be released in November at a similar price point to the original.

  • Program the gold micro:bit logo to respond to your touch

Important Info

Updating .hex files

The editors and apps are being updated over the coming weeks and are currrently in beta. When they are released, you should update any compiled .hex files that you host as part of your resources. To do this, simply drag and drop them into the editor in which they were created and then download the .hex file.

Universal Hex Note that the updated file will be ~1.8Mb as opposed to ~700Kb in size. This increase in size means that the hex file can be used on any board revision and is called a Universal Hex file.

Bluetooth BLE

A hex file that enables all micro:bit Bluetooth services is available to use for testing BLE. Download the updated version of the BLE all services hex.

Code Editors

The editors will support both versions simultaneously for features common to both boards, for example the motion sensor, LEDs, buttons etc.
