Questions
How big is the Elec PCB?
It measures 71.5 × 75.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Elec use?
42 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 Elec KiCad files?
From the izzyhub/bedpresence repository on GitHub, at the commit this page was made from: the board is elec/layout/default/default.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Elec 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).
