Compute Module 4 IO Board

NOTE: Not all features are supported in CircuitPython.

Exposing every interface from Raspberry Pi Compute Module 4, the Compute Module 4 IO Board provides a development platform and reference base-board design for the most powerful Compute Module yet.

The Compute Module 4 IO Board is a development board for those who wish to make use of the Raspberry Pi in a more flexible form factor, intended for industrial applications.

While the Compute Module contains the guts of a Raspberry Pi 4 (1.2GHz, quad-core Broadcom BCM2837 processor), it does not have any easy-to-use ports for development. That’s where this IO Board comes in!

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 will be available on the micro-B connector on the IO board. EMMC compute modules are not supported yet.

CircuitPython 8.0.0-alpha.1

This is the latest unstable release of CircuitPython that will work with the Compute Module 4 IO Board.

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

Release Notes for 8.0.0-alpha.1

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.
