Questions
How big is the Macro pad pcb PCB?
It measures 83.4 × 107.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro pad pcb use?
46 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Macro pad pcb KiCad files?
From the andrewbviola/macro-pad repository on GitHub, at the commit this page was made from: the board is macro-pad-pcb/macro-pad-pcb.kicad_pcb and its schematic macro-pad-pcb/macro-pad-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro pad pcb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
