Questions
What parts does the Player use?
123 parts, built around the CC1101RGP, RDA5807M, LM358 and ME2149FSG. 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 dltech/usb_player repository on GitHub, at the commit this page was made from: the board is sch/player.kicad_pcb. 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 Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
