Overview
Hackpad is an open-source printed circuit board by shlinke, from the shlinke/homePad repository on GitHub. It is a 2-layer board of 66.7 × 69.1 mm with 13 parts on 17 nets, routed with 110 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 6 switches, 4 diodes, 1 IC and 1 connector. It belongs with the keyboards and input boards and the RP2040 boards of this library.

Why did I build this?
Recently, I bought a 60% keyboard, and I miss having the 6 function keys, as I used them very often. This project is a fix for this problem -- a macropad for those extra 6 function keys!

Questions
How big is the Hackpad PCB?
It measures 66.7 × 69.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
13 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 shlinke/homePad 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 shlinke before reusing the design.
