Questions
How big is the Scanner PCB?
It measures 99.1 × 132.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Scanner use?
69 parts, built around the ULN2003A and 74HC595. 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 Scanner KiCad files?
From the cellularmitosis/scanner repository on GitHub, at the commit this page was made from: the board is scanner.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scanner 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).
