Questions
How big is the Controller board PCB?
It measures 233 × 35.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Controller board use?
43 parts. 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 Controller board KiCad files?
From the marcoreps/rotoplexer repository on GitHub, at the commit this page was made from: the board is electronics/controller board/controller board.kicad_pcb and its schematic electronics/controller board/controller board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller board design in my own project?
Its repository states no licence, so its author keeps all rights: ask marcoreps before reusing the design.
