🎉 PI4J joins Commonhaus!

Announcement

Windermere, Florida - All remote – Mar 5th, 2026 – Today, the Commonhaus Foundation is pleased to announce that PI4J joins as a member project.

PI4J has been the Java library for interacting with the Raspberry Pi's GPIO pins and hardware interfaces since 2012. What started as a passion project by Robert Savage has grown into an actively maintained open-source library used by Java developers worldwide to connect their code to the physical world — buttons, LEDs, sensors, displays, and more. The recently released V4, based on the Foreign Function and Memory (FFM) API, shows that it keeps up with the evolution of Java and single-board computers.

Frank Delporte, currently the main communicator and documentation lead of the Pi4J project, shares the following:

Joining the Commonhaus Foundation is a natural next step for the project's long-term sustainability. As with many open-source projects, contributors come and go, and we want to ensure Pi4J can continue, regardless of what happens to the current team members. Commonhaus gets the keys to our critical infrastructure, acting as a neutral anchor that ensures the project can always be handed over and kept alive. Beyond that, we share Commonhaus's values: honoring project identity, keeping governance lightweight, and putting the community first, as that has been the success of the Pi4J project.
