Questions
How big is the Macropad PCB?
It measures 95.5 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
88 parts, built around the RP2040, W25Q128JVSIQ, 1N4148W and WS2812B. 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 devramsean0/copperkeyboard repository on GitHub, at the commit this page was made from: the board is Macropad/macropad.kicad_pcb and its schematic 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 states no licence, so its author keeps all rights: ask devramsean0 before reusing the design.
