Questions
How big is the Keyboard PCB?
It measures 87.6 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
43 parts, built around the AMS1117CD-3.3. 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 Keyboard KiCad files?
From the Delete228/OpenCalc repository on GitHub, at the commit this page was made from: the board is keyboard/pcb/keyboard/keyboard.kicad_pcb and its schematic keyboard/pcb/keyboard/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Delete228 before reusing the design.
