Questions
How big is the Macrooopad PCB?
It measures 65.6 × 81.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macrooopad use?
20 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 Macrooopad KiCad files?
From the nxrmqlly/macrooopad repository on GitHub, at the commit this page was made from: the board is PCB/macrooopad.kicad_pcb and its schematic PCB/macrooopad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macrooopad design in my own project?
Its repository states no licence, so its author keeps all rights: ask nxrmqlly before reusing the design.
