Questions
How big is the Caveboard PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Caveboard use?
44 parts, built around the 74HC244D, 74HC00D, 74HC138 and DS1813-5+. 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 Caveboard KiCad files?
From the and3rson/caveboard repository on GitHub, at the commit this page was made from: the board is kicad/main.kicad_pcb and its schematic kicad/main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Caveboard 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).
