Questions
How big is the Dodecahedron n4 PCB?
It measures 32.5 × 30.9 mm and has 4 copper layers, 1 mm thick.
What parts does the Dodecahedron n4 use?
68 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 Dodecahedron n4 KiCad files?
From the davedarko/LEDodecahedron repository on GitHub, at the commit this page was made from: the board is KiCad Schematics/dodecahedron_n4.kicad_pcb and its schematic KiCad Schematics/dodecahedron_n4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dodecahedron n4 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).
