From the project
Raspberry Pi extension board for the PI1541 project.
This is an IO adapter board for the Raspberry Pi 3, based on the awesome Pi1541 project by Steve White. It is currently very much work in progress. USE AT YOUR OWN RISK!
Details of the adapter board development are documented on hackup.net. The Gerber files for the latest stable revision are included in the repository. Also, the boards are ready to be ordered directly from PCBWay or DirtyPCBs.
