This is an Arduino sketch for DFPlayer Mini MP3 module
written by : enjoyneering
source code: https://github.com/enjoyneering/DFPlayer
DFPlayer Mini features:
- 3.2v..5.0v, typical 4.2v
- 15mA without flash drive, typical 24mA
- 24-bit DAC with 90dB output dynamic range and SNR over 85dB
- micro SD-card, up to 32GB (FAT16, FAT32)
- USB-Disk up to 32GB (FAT16, FAT32)
- supports mp3 sampling rate 8KHz, 11.025KHz, 12KHz, 16KHz, 22.05KHz, 24KHz, 32KHz, 44.1KHz, 48KHz
- supports up to 100 folders, each folder can be assigned to 001..255 songs
- built-in 3W mono amplifier, NS8002 AB-Class with standby function
- UART to communicate, 9600bps (parity:none, data bits:8, stop bits:1, flow control:none)
NOTE:
- if you hear a loud noise, add a 1K resistor in series with DFPlayer TX pin
- move the jumper from right to left to automatically switch the amplifier to standby
