Meet the new BBC micro:bit v2 - Upgraded with a powerful new processor that has tons more capability and also adds more sensing with a new speaker and microphone!

The latest micro:bit will fit right into your existing lessons and materials; all the existing MakeCode blocks and MicroPython code will work in the same way as they do on the original micro:bit. More features, including easy ways to take AI and ML into the classroom, will be released throughout 2021.

It’s the same size and shape as the original micro:bit so you can use the same accessories you already own.

Some new features of the board:

  • A more powerful Nordic nRF52833 processor, lots more RAM and Flash so MicroPython works a lot better!
  • A MEMS microphone, can hear the world around it
  • A speaker, provide audio feedback, play tones
  • Capacitive touch sensor, the logo now acts as a button you can boop!
  • Power saving mode, double click the reset button to enter low power mode.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
