Questions
How big is the Project NuXT PCB?
It measures 184.9 × 243.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Project NuXT use?
223 parts, built around the PIC12F629-I/P, 74F245D, 27C256-17/J and 74F573D. 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 Project NuXT KiCad files?
From the monotech/NuXT repository on GitHub, at the commit this page was made from: the board is Project NuXT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project NuXT 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).
