Standalone DJ System Runs On ESP32

A hobbyist project called Pajoniiir replaces a laptop in a DJ booth with an ESP32-P4 microcontroller paired with a 4.3-inch touchscreen. It connects via USB to a Pioneer DDJ-FLX4 controller and a USB stick holding a Rekordbox music library, while a PCM5102A DAC handles audio output. The system reads MP3, WAV, and FLAC files, responds to controller input, and renders waveforms on screen, all for about $50, avoiding the risk of a laptop freezing or rebooting mid-set.
