Questions
How big is the Keypad PCB?
It measures 66.8 × 97.5 mm and has 2 copper layers, 1 mm thick.
What parts does the Keypad use?
71 parts, built around the 74LVC2T45DC. 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 Keypad KiCad files?
From the zephray/Sharket repository on GitHub, at the commit this page was made from: the board is pcb/keypad/keypad.kicad_pcb and its schematic pcb/keypad/keypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keypad design in my own project?
Its repository states no licence, so its author keeps all rights: ask zephray before reusing the design.
