Questions
How big is the PRO PCB?
It measures 61.9 × 82.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PRO use?
25 parts, built around the SK6812MINI-E. 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 PRO KiCad files?
From the Kingdragoncat/HackPad repository on GitHub, at the commit this page was made from: the board is PCB Pro Files/PRO/PRO.kicad_pcb and its schematic PCB Pro Files/PRO/PRO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PRO design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kingdragoncat before reusing the design.
