CircuitPython 2.2.4

From the GitHub release page:

Another small release for new boards! This release adjusts the status LED brightness. The newer Itsy Bitsy M0 Express, Gemma M0 and Trinket M0 have a new rev of DotStar that changes the brightness curve to be much dimmer at the minimum. The fix finds a middle ground that’s not too bright on old ones and not too dim on new ones.


To install follow the instructions in our new Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.

Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).

All builds except ESP8266 are available as both UF2 and bin files here along with test builds.

Use the mpy-cross executables below to pre-compile .py files to .mpy files. You might need to do this if your .py file is too large to compile on the board. Details here. The 2.2.0 mpy-cross versions are still compatible with this new release.
