About
This was my first hardware project involving CAD. I've only ever worked on breadboards with an Arduino before. So, I had to learn KiCAD and Fusion from scratch to design the board and case.

Questions
How big is the Macropad PCB?
It measures 63 × 99.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
28 parts, built around the SK6812. 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 Macropad KiCad files?
From the wldd22/blueprint-macropad repository on GitHub, at the commit this page was made from: the board is pcb/macropad.kicad_pcb and its schematic pcb/macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask wldd22 before reusing the design.
