Questions
How big is the Macropad9x9 PCB?
It measures 62.1 × 62.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad9x9 use?
32 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 Macropad9x9 KiCad files?
From the PassarinhoAzul/macropad3x3 repository on GitHub, at the commit this page was made from: the board is Hardware Layout/macropad3x3/Macropad9x9.kicad_pcb and its schematic Hardware Layout/macropad3x3/Macropad9x9.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad9x9 design in my own project?
Its repository states no licence, so its author keeps all rights: ask PassarinhoAzul before reusing the design.
