Questions
How big is the One button interface PCB?
It measures 18 × 36 mm and has 4 copper layers, 1.6 mm thick.
What parts does the One button interface use?
15 parts, built around the LD39015M33R. 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 One button interface KiCad files?
From the yannidd/one-button-interface repository on GitHub, at the commit this page was made from: the board is pcb/kicad/one_button_interface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the One button interface design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
