The Arduino MKR ZERO brings you the power of a Zero in the smaller format established by the MKR form factor. The MKR ZERO board acts as a great educational tool for learning about 32-bit application development. The board is powered by Microchip’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core.

This is the latest stable release of CircuitPython that will work with the MKR Zero.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the MKR Zero.
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.
