micro:bit Beta Testing Programme

Help us improve micro:bit by trying out new software!

Do you enjoy finding bugs and suggesting improvements? Then we and the entire micro:bit community need your help!

The Foundation is committed to producing the very best software and hardware that inspires every child. We can only do that by getting feedback on the things we're making.

If you take on the challenge and become a micro:bit tester, you'll have the power to shape the tools we make: fix things that don't work for you, improve the instructions and documentation, and suggest ideas we'd never even have thought of.

To get started as a tester, sign up to the mailing list by clicking the button below, and we'll start telling you about all the latest software before we release it to the rest of the world. Please note that the beta testing programme is only open to those 13 and over.

Our testing programmes

    Flashing via Web USB

    WebUSB is a technology that enables a direct connection between the micro:bit and your web browser.


      Testing the latest version of the Python Editor.

      Flashing the micro:bit directly with WebUSB

      WebUSB is a technology that enables two exciting possibilities:

      1. We can program the micro:bit directly from the editors, without the drag-and-drop step you're used to!
      2. You can receive serial communication from the micro:bit directly to the browser. This will be really useful for things like Python where the 'REPL' is an important part of learning to code, but currently isn't available in the online editor at python.microbit.org.

      webUSB is an emerging web standard that lets the browser (where our micro:bit editors normally run) talk directly to devices using USB. As the micro:bit works using USB, it's possible to upgrade the 'interface firmware' on the micro:bit in order to give it new webUSB powers. This is all quite new technology, and so there are a few rough edges.

      At the moment, only Chrome supports webUSB.

      What we need to test:

      As this process requires a micro:bit firmware upgrade, we need to test that the instructions for updating the firmware are clear. We want to test webUSB on as many different systems as we can, and find out whether the instructions are clear. We aren't yet looking for feedback on the way that we initiate webUSB connections in the editors -- the user interface that we're showing during the testing programme is not final and we expect to create something smoother during the beta period. When you sign up, you'll get a detailed list of instructions for testing.

      Where do I report bugs?

      There are a few different moving parts here, so please see the Knowledge Base article for where to file bugs, or submit a support ticket.

      Python Editor Version 2

      Get it Here

      The Python Editor beta contains a range of UX changes and features that will soon be coming to Version 2.

      What we need to test:

      Head to the Python Editor beta and click on Help to check the Editor Version contains a reference to version 2 eg '2.0.0-beta.3'. If this is not the case, you may need to refresh your browser cache. Some of these features will only work in a Chrome-based browser (Google Chrome, Edge Beta, Opera etc) as they rely on WebUSB.

      We would really appreciate feedback on the general User Experience (UX). We’ve fixed a variety of bugs on some of the features listed below and updated the menu, so we’d like you to test these out and let us know how they work for you prior to finalising our Version 2 release. Once we've got some feedback on this, we'll be finalising a release candidate, where we'd like you to test the features and report any other bugs prior to the release. You can read more about Python Editor Version 2 in our help article.

      • The FileSystem and using modules
      • WebUSB, flashing and REPL (Chrome-based only)
      • Quick Flash, enabling the rapid updating of the micro:bit (beta option)
      • Autocompletion (beta option)
      • Translation functionality (this is basic for now, but should give you an idea of what is possible).

      We would encourage you to use the beta as you would in your everyday activities.

      Where do I report bugs?

      Please raise a support ticket including as much information as possible about your system and the issue.

      If you have a GitHub account, you can report issues directly on the source repository.
