Description
Overview
The DFPlayer Mini MP3 Module is a compact, low-cost MP3 playback module designed for Arduino, ESP32, Raspberry Pi, and other micro-controllers. It features built-in MP3 decoding, allowing it to play audio files directly from a micro-SD card (up to 32GB) without requiring an external decoder or amplifier.
With serial (UART), button control, and AD key mode, the DFPlayer Mini provides easy integration into embedded systems, sound effects applications, and automation projects. It includes a built-in 3W amplifier, making it suitable for direct speaker output or connection to an external amplifier for enhanced sound quality.
