Questions
How big is the Macropad PCB?
It measures 63 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
9 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 sqnder0/macropad repository on GitHub, at the commit this page was made from: the board is PCB/macropad.kicad_pcb and its schematic PCB/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 sqnder0 before reusing the design.
