Questions
How big is the 3x3macropad PCB?
It measures 59.7 × 81.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 3x3macropad use?
23 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 3x3macropad KiCad files?
From the prlowe/Macropad repository on GitHub, at the commit this page was made from: the board is 3x3macropad-main/3x3macropad/3x3macropad.kicad_pcb and its schematic 3x3macropad-main/3x3macropad/3x3macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 3x3macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask prlowe before reusing the design.
