Questions
How big is the Hackpad PCB?
It measures 64.2 × 87.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
21 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 KiCad files?
From the hashim-cpro/hackpad repository on GitHub, at the commit this page was made from: the board is PCB/Hackpad.kicad_pcb and its schematic PCB/Hackpad.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 hashim-cpro before reusing the design.
