Questions
How big is the Corneds PCB?
It measures 309.4 × 105.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Corneds use?
126 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 Corneds KiCad files?
From the Entropy98/corneds_pcb repository on GitHub, at the commit this page was made from: the board is corneds.kicad_pcb and its schematic corneds.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Corneds design in my own project?
Its repository states no licence, so its author keeps all rights: ask Entropy98 before reusing the design.
