Questions
How big is the Brain PCB?
It measures 48 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Brain use?
38 parts, built around the RP2040, W25Q128JVSIQ, AMS1117-3.3 and 1N5819WS. 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 scottcjx/brain repository on GitHub, at the commit this page was made from: the board is HDK/brain/brain.kicad_pcb and its schematic HDK/brain/Connectors.kicad_sch. 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 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).
