Questions
How big is the Rock audio PCB?
It measures 56 × 65 mm and has 2 copper layers, 1 mm thick.
What parts does the Rock audio use?
59 parts, built around the ES8388, ME6211C33M5G-N and IM73A135V01. 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 Rock audio KiCad files?
From the artixzhang/rock-module repository on GitHub, at the commit this page was made from: the board is rock_audio/rock_audio.kicad_pcb and its schematic rock_audio/rock_audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rock audio 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).
