Questions
How big is the Cube PCB?
It measures 44 × 44 mm and has 2 copper layers, 1 mm thick.
What parts does the Cube use?
75 parts, built around the ATTINY1604-SSF, ATTINY402-SSN, CH340E and PAM8406DR. 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 McbeEringi/pcb-stuff repository on GitHub, at the commit this page was made from: the board is proj/musicbox/cube/cube.kicad_pcb. 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 MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
