Archived as there are too many problems:
- Need a resister per RGB input, not one per output, as constant current across the RGBLED distorts the color otherwise. That's a lot of SMD components.
- The RPi Pico has a limited number of PWM units, not enough for running all of the RGBLEDs, and they were hooked up incorrectly anyway.
- Idea was ditched in favor of streamdekc instead.

Questions
How big is the Macropad PCB?
It measures 124.5 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad 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 Macropad KiCad files?
From the meh2481/macropad repository on GitHub, at the commit this page was made from: the board is KiCad/macropad/macropad.kicad_pcb and its schematic KiCad/macropad/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 publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
