Questions
How big is the L0 button PCB?
It measures 20.3 × 15.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the L0 button use?
2 parts. 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 L0 button KiCad files?
From the Luos-io/luos_engine repository on GitHub, at the commit this page was made from: the board is examples/hardware/l0-shields/l0_button/l0_button.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the L0 button design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
