Questions
How big is the Hackpad v2 PCB?
It measures 98 × 65.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad v2 use?
15 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 v2 KiCad files?
From the MasterClassmate3004/SpacePad repository on GitHub, at the commit this page was made from: the board is PCB/hackpad_v2.kicad_pcb and its schematic PCB/hackpad_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MasterClassmate3004 before reusing the design.
