Questions
How big is the Double action keyboard PCB?
It measures 132 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Double action keyboard use?
151 parts, built around the 1N4148W. 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 Double action keyboard KiCad files?
From the kenyahiro/double-action-keyboard repository on GitHub, at the commit this page was made from: the board is sch/double-action-keyboard/double-action-keyboard.kicad_pcb and its schematic sch/double-action-keyboard/double-action-keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Double action keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask kenyahiro before reusing the design.
