Questions
How big is the Player PCB?
It measures 56.5 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Player use?
12 parts. 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 Player KiCad files?
From the rubaiyat666/dB-1 repository on GitHub, at the commit this page was made from: the board is player/player.kicad_pcb and its schematic player/player.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Player 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).
