Questions
How big is the (N)OR PCB?
It measures 69.9 × 74.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the (N)OR use?
18 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 (N)OR KiCad files?
From the csBlueChip/CPU_HowTo repository on GitHub, at the commit this page was made from: the board is KiCAD/(N)OR/(N)OR.kicad_pcb and its schematic KiCAD/(N)AND/(N)AND.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the (N)OR 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).
