Questions
How big is the Brain PCB?
It measures 78 × 55 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Brain use?
106 parts, built around the XC7S15-1FTGB196C, INA216A2RSW, S25FL128SAGBHI300 and CB3LV-3C-25M000000. 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 Brain KiCad files?
From the azonenberg/sky130-validation repository on GitHub, at the commit this page was made from: the board is or1/boards/brain/brain.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brain design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
