this macropad was made for hackpad (a program by hackclub) back in febuary 2025! I have still yet to assemble it, but I found these files and wanted to reupload them somewhere. I'll post images as soon as I finish it!
yet another keypad lmao, may reprogram in the future

Questions
How big is the Hackpad PCB?
It measures 90 × 107 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
34 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 piplup7575/piplhackpad 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 piplup7575 before reusing the design.
