Zero

by Raspberry Pi

Image of Board

NOTE: Not all features are supported in CircuitPython.

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 its early developments.

After installing the disk image on an SD card, the normal CircuitPython USB workflow is available over the micro-B USB connector labeled “USB”.

CircuitPython 7.3.0-rc.0

This is the latest unstable release of CircuitPython that will work with the Zero.

Unstable builds have the latest features but are more likely to have critical bugs.

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. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
