Questions
How big is the Macropad1 PCB?
It measures 139.7 × 69.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad1 use?
77 parts, built around the ATMEGA32U4-AU and 24LC512-I/P. 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 Macropad1 KiCad files?
From the eeble/myfirstmacropad repository on GitHub, at the commit this page was made from: the board is kicad/macropad1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad1 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
