Questions
How big is the Input Switch 8X PCB?
It measures 133 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Input Switch 8X use?
86 parts, built around the AO3400A, BC817 and BZT52C10. 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 Input Switch 8X KiCad files?
From the koson/Input_Switch_8X repository on GitHub, at the commit this page was made from: the board is Input_Switch_8X.kicad_pcb and its schematic Input_Switch_8X.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Input Switch 8X design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
