The Adafruit Feather M0 Express was one of the first development boards designed for CircuitPython by Adafruit. Unlike the original Feather M0 Basic, it added a NeoPixel status LED and external 2MB SPI Flash for storing CircuitPython code.
It is a great entry into the Feather ecosystem with CircuitPython. However, it is now out performed by the Feather M4 Express which has a faster microcontroller with more RAM. The additional RAM allows CircuitPython to load more code all at once than this Feather M0 Express can.
This is the latest stable release of CircuitPython that will work with the Feather M0 Express.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the Feather M0 Express.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.
All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
