Mini MP3 Player

Mini MP3 Player is a compact and inexpensive MP3 module that can be connected directly to the speaker. The module can be used alone with a battery power supply, speaker, and keypad, or through the serial port control, as the Arduino UNO compatible board or any microcontroller with a serial port module. The module itself perfectly integrated hardware decodes MP3, WAV, and WMA's. The software supports TF card drivers to support FAT16, FAT32 file systems. This can be done by the simple serial command that plays the specified music, as well as how to play music and other functions, easy to use, stable and reliable.

Play next MP3 every 8 second.
