Questions
How big is the Bigmax PCB?
It measures 190.5 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bigmax use?
31 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 Bigmax KiCad files?
From the ideometre/BigMax repository on GitHub, at the commit this page was made from: the board is électronique/KiCad/bigmax/bigmax.kicad_pcb and its schematic électronique/KiCad/bigmax/bigmax.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bigmax design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
