It has a rotary encoder for volume, 4 keys for media control with an extra one for anything that might be useful and a OLED to show information about the media.
This is my first time doing any PCB and CAD work, so hopefully there isn't a mess

Questions
How big is the Hackpad PCB?
It measures 99 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
14 parts, built around the SK6812MINI-E. 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 Fleny113/hackpad-blueprint 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 Fleny113 before reusing the design.
