YX5300 MP3 Music Player Module: Versatile Audio Control

Enhance your projects with the YX5300 MP3 Music Player Module. This versatile module offers high-quality MP3 audio playback and supports various file formats (8kHz-48kHz). Easily control playback functions (songs, volume, mode) using UART commands from your MCU (Arduino, AVR, ARM, PIC). The built-in TF card slot allows for convenient audio file storage.

Features:

1. Support sampling frequency (kHz): 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48
2. Support file format: MP3 / WAV
3. Support Micro SD card, Micro SDHC Card
4. 30 class adjustable volume
5. UART TTL serial control playback mode, baud rate is 9600bps
6. Power supply can be 3.2 ~ 5.2VDC

Instructions/ helpful Code:

Save mp3 files in sd card and here is test code

send + to arduino from serial terminal of arduino for next song and – for previous song.
