Compute Module 4 IO Board

Image of Board

NOTE: This build is alpha quality and is for experimental use. It is missing features and has known issues.

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 early development.

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.

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.
