Questions
How big is the Hackpad copy PCB?
It measures 80 × 81.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad copy use?
14 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 Hackpad copy KiCad files?
From the smallzdev/flight-sim-hackpad repository on GitHub, at the commit this page was made from: the board is pcb/hackpad copy.kicad_pcb and its schematic pcb/hackpad copy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad copy design in my own project?
Its repository states no licence, so its author keeps all rights: ask smallzdev before reusing the design.
