Questions
How big is the Enter button PCB?
It measures 120 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Enter button use?
20 parts, built around the AMS1117-3.3. 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 Enter button KiCad files?
From the 123khg/Big-Enter-Button repository on GitHub, at the commit this page was made from: the board is enter button/enter button.kicad_pcb and its schematic enter button/enter button.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Enter button design in my own project?
Its repository states no licence, so its author keeps all rights: ask 123khg before reusing the design.
