Open Source Mini MP3 Player Mini Player MP3 Player Playback Module

Overview

DFPlayer Mini is a compact and low-cost MP3 module that can be directly connected to the speaker. The module can be used alone with the power supply battery, speaker, and buttons, or can be controlled through the serial port, as a module of UNO or any single-chip microcomputer with a serial port. The module itself perfectly integrates the hard decoding of MP3, WAV and WMA. At the same time, the software supports TF card driver and FAT16, FAT32 file system. The functions of playing the specified music and how to play the music can be completed through simple serial port commands, without the need for cumbersome low-level operations, easy to use, stable and reliable.
