About the BBC micro:bit

The BBC micro:bit is a handheld, fully programmable computer given free to every Year 7 student across the UK.

We're very excited about the opportunities for learning and teaching programming. We teach MicroPython, a lean and fast implementation of the Python 3 for microcontrollers.

We've created a full micro:bit simulator in the browser so students can learn how to program a physical device before tackling all the issues that come with a physical device. We've also developed learning materials with automated marking to help teachers use the BBC micro:bit effectively as a teaching tool in the classroom.

Frequently Asked Questions

Do I need a micro:bit to use these resources?

No. We've created a full micro:bit simulator so you can do everything you'd do on a real micro:bit in the browser. Learn how to program a physical device before tackling all the issues that come with a physical device.

Can download code I write in Grok to my device?

Yes. You can download any programs you write on our platform to run on your real micro:bit. Use our editor to write and test programs for your micro:bit.

Where can I purchase a BBC micro:bit?

You can order individual/small quantities from approved resellers. Check the shipping policies to see if they ship to your country.
