Questions
How big is the Beats PCB?
It measures 60 × 106.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Beats use?
123 parts, built around the 74AHCT244D, MCP6004-E/P, L7805 and LM1117-3.3. 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 Beats KiCad files?
From the marangisto/Beats repository on GitHub, at the commit this page was made from: the board is Beats.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beats 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).
