This is supposed to be a keyboard macro pad that lets you set keys to custom keybinds, using mx switches, a rotary knob, and LEDs.
My attempt at a start-to-finish hardware project from scratch, including creating PCB designs, 3d print designs, and coding firmware.

Questions
How big is the CommandPad PCB?
It measures 90 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CommandPad use?
21 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 CommandPad KiCad files?
From the sjalkote/CommandPad repository on GitHub, at the commit this page was made from: the board is PCB/CommandPad.kicad_pcb and its schematic PCB/CommandPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CommandPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask sjalkote before reusing the design.
