Questions
How big is the Prawowity hackpad PCB?
It measures 76.4 × 83.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prawowity hackpad use?
20 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 Prawowity hackpad KiCad files?
From the Kabanosik230/hackpad repository on GitHub, at the commit this page was made from: the board is PCB/prawowity hackpad.kicad_pcb and its schematic PCB/prawowity hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prawowity hackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kabanosik230 before reusing the design.
