Questions
How big is the Cube PCB?
It measures 78.7 × 47.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cube use?
19 parts, built around the BC337. 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 Cube KiCad files?
From the CUBE-SD-Project/cube-neuro repository on GitHub, at the commit this page was made from: the board is EDA/cube/cube.kicad_pcb and its schematic EDA/cube/cube.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cube 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).
