Questions
How big is the NBoxRpi PCB?
It measures 68 × 86.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NBoxRpi use?
95 parts, built around the 74HC541D, MCP3002-I/P, TLP222AF and DS1307+. 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 NBoxRpi KiCad files?
From the trihome/RasPi_NervesBOX repository on GitHub, at the commit this page was made from: the board is NBoxRpi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NBoxRpi design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
