Questions
How big is the Big Honking Button PCB?
It measures 40.1 × 49.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Big Honking Button use?
54 parts, built around the 74AHCT1G125SE, GD25Q64CFIG, TL072 and AP2112K-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 Big Honking Button KiCad files?
From the wntrblm/Big_Honking_Button repository on GitHub, at the commit this page was made from: the board is hardware/board/board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Big Honking Button design in my own project?
Its repository states no licence, so its author keeps all rights: ask wntrblm before reusing the design.
