Questions
How big is the 3x3Macro PCB?
It measures 60 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 3x3Macro use?
19 parts, built around the 1N4148WT. 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 3x3Macro KiCad files?
From the bbryan8910/3x3-Macropad repository on GitHub, at the commit this page was made from: the board is PCB/3x3Macro.kicad_pcb and its schematic PCB/3x3Macro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 3x3Macro design in my own project?
Its repository states no licence, so its author keeps all rights: ask bbryan8910 before reusing the design.
