Serial Mp3 Module Sensor

The serial mp3 module sensor 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. By liking Our Facebook Page Embeded Studio , you can get special discount.
