Questions

How big is the Hackpad PCB?

It measures 61.1 × 46.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hackpad use?

6 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 Nat3z/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 Nat3z before reusing the design.
