Zero W

by Raspberry Pi

Image of Board

NOTE: Not all features are supported in CircuitPython.

Raspberry Pi Zero W Is the first small size (Wifi enabled) Raspberry Pi’s single-board computers. This is the predecessor of Raspberry Pi Zero 2 W with the same form factor.

The board incorporates a Broadcom single-core ARMv6 CPU (BCM2835) clocked at 1GHz and has 512MB of RAM.

The board has a microSD card slot, a CSI-2 camera connector, a USB On-The-Go (OTG) port, and an unpopulated footprint for a HAT-compatible 40-pin GPIO header. It is powered via a micro USB socket. Video output is via a mini HDMI port; composite video output can easily be made available via test points, if needed.


These downloads are for CircuitPython standalone on the Raspberry Pi (not Blinka). There is no underlying operating system. It is in its early developments.

This image could work on non Wifi Pi Zero but was primarly develop for the Wifi version.

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. 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.
