Firmware
The firmware is set up with a basic keymap. The display should also work, though I will have to test it. Might switch to the RMK frimware in the future.

Questions
How big is the Hackypad PCB?
It measures 62 × 79.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackypad use?
24 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 Hackypad KiCad files?
From the FraI3mega/hackypad repository on GitHub, at the commit this page was made from: the board is PCB/hackypad.kicad_pcb and its schematic PCB/hackypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackypad design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
