The DFPlayer Mini MP3 Player For Arduino is a small and low price 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 an Arduino UNO or any other with RX/TX capabilities.
SPECIFICATION
- Supported sampling rates (kHz): 8/11.025/12/16/22.05/24/32/44.1/48
- 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
- A variety of control modes, I/O control mode, serial mode, AD button control mode
- Advertising sound waiting function, the music can be suspended. when advertising is over in the music continue to play
- Audio data sorted by folder supports up to 100 folders, every folder can hold up to 255 songs
- 30 level adjustable volume, 6 -level EQ adjustable
NOTE: Need 5V to drive the speaker.

Copying Mp3s to your Micro SD Card
Format your micro SD card as FAT32.
Copy the mp3 files to the SD Card
Code Block |
---|
cp } } |
...
*.mp3 /Volumes/<VOLUME_NAME>/. |
Remove all unneeded files if on a MAC
Code Block |
---|
dot_clean /Volumes/<VOLUME_NAME> |
NOTE: The order you copy the mp3 into micro SD card will affect the order mp3 played , which means play(1) function will play the first mp3 copied into micro SD card.
