Feather M0 Express

by Adafruit

Image of Board

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.

Absolute Newest

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.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
