Overview

Thank you, content producers, for your support of the micro:bit - without people writing amazing resources and showing the world creative ways to use technology, micro:bit wouldn’t be nearly as exciting for people all around the world to use.


If you’d like to keep up to date with technical information about the device, please sign up to our DAL, Devices and Editors mailing list which provides information on hardware revisions, or key low-level software changes as early as possible.

Updating .hex files

If you host compiled .hex files as part of your resources, these will need to be updated to work with the latest revision of the micro:bit.


The editors and apps are currently in beta, so you should wait to do this until they are made live over the coming weeks before updating the files.


To do update them, 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.
