DF MP3 Player Audio Voice Module 

The DFPlayer Mini MP3 Player For Arduino is a small and low cost MP3 module with an simplified output directly to the speaker. The module can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with microcontrollers such as Arduino, ESP32, Raspberry Pi and any microcontrollers with Uart.

It is supported sampling rates (kHz): 8/11.025/12/16/22.05/24/32/44.1/48 and 24 -bit DAC output, support for dynamic range 90dB, SNR support 85dB. fully supports FAT16, FAT32 file system, maximum support 32G of the TF card, support 32G of U disk, 64M bytes NOR FLASH and a variety of control modes, I/O control mode, serial mode, AD button control mode advertising sound waiting for function, the music can be suspended. When advertising is over within the music still play, audio data sorted by folder supports up to 100 folders, every folder can delay to 255 songs, 30 level adjustable volume, 6 -level EQ adjustable. The Arduino must communicate via the serial with the DFMini Player and send the control commands. Based on this, the module are often controlled via the standalone mode, that is, during this mode, there'll only be the DFMini module, A battery to power, the speaker, buttons to control it, and the SD card with the songs.
