Questions
How big is the CTRL PCB?
It measures 196.5 × 151.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CTRL use?
127 parts, built around the MCP3008-I/P, SK6812MINI-E, RKJXT1F42001 and RKJXV122400R. 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 CTRL KiCad files?
From the JustAGlitchFL/CTRL repository on GitHub, at the commit this page was made from: the board is CTRL (Left)/CTRL/CTRL.kicad_pcb and its schematic ALT (Right)/ALT/ALT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CTRL design in my own project?
Its repository states no licence, so its author keeps all rights: ask JustAGlitchFL before reusing the design.
