Questions
How big is the Rpi interface PCB?
It measures 102.2 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rpi interface use?
30 parts, built around the MCT6 and ULN2003. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Rpi interface KiCad files?
From the johnerlandsson/cb50_ctrl repository on GitHub, at the commit this page was made from: the board is schematic/rpi_interface/rpi_interface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rpi interface design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
