From the project

Portable ESP 32 based MP3 Player

A compact, self-contained portable audio player built around the ESP32, featuring a colour TFT display, USB-C LiPo charging, stereo headphone output, and mono speaker output. Supports MP3, WAV, and FLAC playback from a MicroSD card.

Designed in KiCad 9.0.6. See hardware/MP3.kicadsch`.

2-layer board. See hardware/MP3.kicadpcb`.

Battery charges at 1A via TP4056 when USB-C is connected. CC1/CC2 pull-down resistors (5.1kΩ) negotiate 5V from the host without requiring USB PD.
