Description

YX5300 UART Control Serial MP3 Music Player Module For Arduino/AVR/ARM/PIC. The module is a kind of simple MP3 player device which is based on a high-quality MP3 audio chip—YX5300. It can support 8k Hz~ 48k Hz sampling frequency MP3 and WAV file formats. There is a TF card socket on board, so you can plug the micro SD card that stores audio files. MCU can control the MP3 playback state by sending commands to the module via UART port, such as switch songs, change the volume and play mode and so on. You can also debug the module via USB to UART module. It is compatible with Arduino/AVR/ARM/PIC.

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.
