Questions
How big is the MP3 Player PCB?
It measures 47.4 × 68.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MP3 Player use?
16 parts, built around the CH340C, ESP32-WROVER-E(4MB) and FSM8JH. 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 MP3 Player KiCad files?
From the Hasnat4763/Shanda-Pod-v1 repository on GitHub, at the commit this page was made from: the board is PCB/MP3_Player.kicad_pcb and its schematic PCB/MP3_Player.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MP3 Player design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hasnat4763 before reusing the design.
