Questions
How big is the Macropad PCB?
It measures 103.5 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
34 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 00jacko00/16-Key-Hackpad repository on GitHub, at the commit this page was made from: the board is Macropad.kicad_pcb and its schematic 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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
