Questions
How big is the MacropadRP2040 PCB?
It measures 95 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacropadRP2040 use?
27 parts, built around the RP2040-ZERO, 1N4148W, WS2812B and AO3400A. 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 MacropadRP2040 KiCad files?
From the po1sonbit/MacropadRP2040 repository on GitHub, at the commit this page was made from: the board is MacropadRP2040.kicad_pcb and its schematic MacropadRP2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacropadRP2040 design in my own project?
Its repository states no licence, so its author keeps all rights: ask po1sonbit before reusing the design.
