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.

If you're in the UK, you can also place large orders with Farnell element14.
