Questions
How big is the Macropad PCB?
It measures 85.1 × 119.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
77 parts, built around the ESP32-S2-MINI-1-N4, AMS1117-3.3, WS2812B and SS8050-G. 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 Bdenouden/macropad repository on GitHub, at the commit this page was made from: the board is PCB/macroPad/macroPad.kicad_pcb. 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 Bdenouden before reusing the design.
