Questions
How big is the NaturalKeyboard PCB?
It measures 438.2 × 133.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NaturalKeyboard use?
235 parts, built around the ATMEGA32U4-MU and 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 NaturalKeyboard KiCad files?
From the cyberknet/NaturalKeyboard repository on GitHub, at the commit this page was made from: the board is NaturalKeyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NaturalKeyboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
