The DFPlayer Mini is a small and low-cost MP3 module player with a simplified output directly to a speaker. The DFPlayer mini can be used as a stand-alone module with an attached battery, speaker, and push buttons or used in combination with an Arduino Uno or any other dev board with RX/TX capabilities.
This MP3 player integrates a hard decoding module, which supports common audio formats such as MP3, WAV, and WMA. The module also supports microSD cards with a FAT16 or FAT32 file system. Through a simple serial port, you can play the designated music file without any other tedious underlying operations.
