Questions
How big is the Macropad PCB?
It measures 91.5 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
14 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 MelonMars/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 MelonMars before reusing the design.
