Zero
by Raspberry Pi
NOTE: This build is alpha quality and is for experimental use. It is missing features and has known issues.
At first glance, the Pi Zero isn’t much. It just looks like a slimmed down version of the Raspberry Pi we know and love. But when we started to think of the possibilities - and what a well-chosen set of accessories could add - we realized the appeal. And then we saw the price…could it be true? Yes!
This is the slimmest, most pared down Raspberry Pi to date. It’s kind of like the little cousin to the Pi 2 - with just a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, similar to the Pi A+ and B+.
CircuitPython
These downloads are for CircuitPython standalone on the Raspberry Pi (not Blinka). There is no underlying operating system. It is in early development.
After installing the disk image on an SD card, the normal CircuitPython USB workflow is available over the micro-B USB connector labeled “USB”.

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.
