Questions
How big is the Cuspid40 PCB?
It measures 276.2 × 91 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cuspid40 use?
154 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 Cuspid40 KiCad files?
From the Daigher/Cuspid40 repository on GitHub, at the commit this page was made from: the board is Cuspid40/Cuspid40.kicad_pcb and its schematic Cuspid40 Backplate/Cuspid40 Backplate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cuspid40 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).
