UART TTL Serial MP3 Music Player Module

Product Description

The UART MP3 Module is a compact audio playback module based on the YX5300/JL high-quality MP3 audio chip, designed to add MP3 and WAV playback functionality to electronic projects. It features an onboard TF card slot for storing audio files and can be controlled through a UART serial interface.

The module allows a microcontroller to send commands for song selection, volume adjustment, playback control, and play-mode selection. It is compatible with popular platforms such as Arduino, AVR, ARM, and PIC, making it suitable for a wide range of embedded and DIY applications.

The module supports sampling frequencies from 8kHz to 48kHz and provides a simple way to integrate audio playback into interactive projects, voice systems, alarms, and electronic devices. Depending on stock availability, the module may use a YX5300 or JL IC.

Working Principle

Audio files are stored on a TF card and accessed by the module during playback. A connected microcontroller communicates with the module through the UART interface and sends commands to select songs, control playback, adjust volume, and change playback modes.

The module processes the selected audio file through its onboard MP3 audio chip and produces the corresponding audio output for connection to a suitable audio system.
