The module is a kind of 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 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.

There is a TypeC-Compatible port on the board, so you can copy some MP3 files to the TF card you plug in the socket via the USB cable without extra TF card reader. The MP3 chip can help your PC to find the TF card via the typeC cable.
