Questions
How big is the CP297s PCB?
It measures 155.1 × 156 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CP297s use?
128 parts, built around the 74LS245SC, 74LS125DC, 74HC74D and 74LS32SC. 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 CP297s KiCad files?
From the Danjovic/CP297s repository on GitHub, at the commit this page was made from: the board is CP297s.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CP297s design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
