Questions
How big is the Microbrain PCB?
It measures 51 × 21 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Microbrain use?
10 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 Microbrain KiCad files?
From the 4f48/microbrain repository on GitHub, at the commit this page was made from: the board is microbrain.kicad_pcb and its schematic microbrain.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Microbrain design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
