Questions
How big is the Hacker Macropad PCB?
It measures 80.1 × 76.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hacker Macropad use?
27 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 Hacker Macropad KiCad files?
From the Nitin-2468-dev/Hacker-Macropad repository on GitHub, at the commit this page was made from: the board is pcb/Project.kicad_pcb and its schematic pcb/Project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hacker Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nitin-2468-dev before reusing the design.
