Overview
The DFPlayer Mini is a compact and affordable MP3 module that can be connected directly to the speakers. The module can be used alone with the power supply battery, speakers, and buttons. It can also be controlled by the serial port as a module of UNO or any single-chip microcomputer with serial port. The module itself integrates the hard decoding of MP3, WAV and WMA perfectly. At the same time, the software supports TF card driver and supports FAT16 and FAT32 file systems. Through the simple serial port command, you can complete the playback of the specified music, and how to play music and other functions, without the cumbersome underlying operation, easy to use, stable and reliable.
