Questions
How big is the Macropad PCB?
It measures 138.5 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
38 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 dialgorithm/macropad repository on GitHub, at the commit this page was made from: the board is KiCad/macropad.kicad_pcb and its schematic KiCad/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 dialgorithm before reusing the design.
