Questions
How big is the Checkinator PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Checkinator use?
16 parts, built around the WS2812. 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 Checkinator KiCad files?
From the GeoffWilliams/checkinator repository on GitHub, at the commit this page was made from: the board is kicad/checkinator.kicad_pcb and its schematic kicad/checkinator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Checkinator 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).
