Questions
How big is the AerospaceBigButton PCB?
It measures 114.2 × 80.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AerospaceBigButton use?
25 parts, built around the AMS1117-5.0 and MMBT2222A. 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 AerospaceBigButton KiCad files?
From the Kev1n8088/AerospaceBigButton repository on GitHub, at the commit this page was made from: the board is AerospaceBigButtonKicad/AerospaceBigButton.kicad_pcb and its schematic AerospaceBigButtonKicad/AerospaceBigButton.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AerospaceBigButton design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kev1n8088 before reusing the design.
