This modules is a simple MP3 player device which is based on a high-quality MP3 audio chip. 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 in the micro SD card that stores audio files. MP3 Playback can be controlled via a Microcontroller such as an Arduino by sending commands to the module via serial UART port, e.g. switch songs, change the volume, play mode and so on. It is compatible with most Microcontrollers capable of serial communication at 9600 BAUD (Arduino / AVR / ARM / PIC). The module also includes a 3 Watt amplifier and comes complete with a 1 Watt speaker.

For Arduino users we have created an exclusive library (HCMP3) which can be downloaded from the software section of our support forum (see link below).
