Mini MP3 Module

The Mini MP3 Module is a small, low-cost mp3 module with a simplified audio output that can be connected directly to a speaker or an earphone jack. The module can be used as a stand-alone module with attached battery, speaker, and push buttons or used in combination with a microcontroller or development board like the Arduino. The full-duplex RX/TX (Serial) communication provides full navigation control and triggering such as playing music and perform other functions like playing the next and previous song, shuffle, pause the song currently being played etc. In addition, the module has a built-in 3 watts amplifier that can directly drive a 3W speaker. The module comes with an SDcard slot and supports both FAT16, FAT32 file system.

This Mini MP3 Module can be used as a stand alone audio module with attached battery, speaker and push buttons or used in combination with an Arduino or any other microcontroller with RX/TX capabilities.
