Questions
How big is the MacroBoard PCB?
It measures 185 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacroBoard use?
64 parts, built around the MCP3008-I/P, 1N4148W and SK6812MINI-E. 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 MacroBoard KiCad files?
From the LoreSchaeffer/MacroBoard repository on GitHub, at the commit this page was made from: the board is PCB/MacroBoard.kicad_pcb and its schematic PCB/MacroBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacroBoard 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).
