Questions
How big is the Hackpad PCB?
It measures 76.6 × 62.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
10 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 Hackpad KiCad files?
From the SPGPaul/Hackpad repository on GitHub, at the commit this page was made from: the board is PCB/Board.kicad_pcb and its schematic PCB/Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask SPGPaul before reusing the design.
