Questions

How big is the Mp3Player PCB?

It measures 93.6 × 94.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Mp3Player use?

65 parts, built around the ESP32-WROOM-32E, EWM104-BT61SP, CH340X and PCM5122PW. 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 Mp3Player KiCad files?

From the Tritonsspace/MP3PlayerPCB repository on GitHub, at the commit this page was made from: the board is Mp3Player.kicad_pcb and its schematic Mp3Player.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mp3Player design in my own project?

Its repository states no licence, so its author keeps all rights: ask Tritonsspace before reusing the design.
