Questions
How big is the 28byj controller PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 28byj controller use?
18 parts, built around the ULN2803A. 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 28byj controller KiCad files?
From the cgbriggs99/InstrumentController repository on GitHub, at the commit this page was made from: the board is circuits/28byj_controller_proto/28byj_controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 28byj controller design in my own project?
Its repository publishes it under the EPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
