BBC micro:bit MicroPython documentation


The BBC micro:bit is a small computing device for children. One of the languages it understands is the popular Python programming language. The version of Python that runs on the BBC micro:bit is called MicroPython.

This documentation includes lessons for teachers and API documentation for developers (check out the index on the left). We hope you enjoy developing for the BBC micro:bit using MicroPython.


The BBC micro:bit MicroPython documentation contains information for all versions of the micro:bit board. Where functionality is applicable only to the latest device, you will see a note or comment marking this as V2.

If you’re a new programmer, teacher or unsure where to start, begin with the tutorials.



This project is under active development. Please help other developers by adding tips, how-tos, and Q&A to this document. Thanks!
