NEXT: short-press to skip to the next song

VOL+: long-press to increase the volume


BACK: short-press to skip to the previous song

VOL-: long-press to decrease volume


EQ: adjust sound effects


Note: The board will output adequate power only when the audio input and power source voltage/current are sufficient. The higher the power supply voltage, the larger the output power. Besides that, speaker impedance also changes the amplifier board power output. Please note that in the case of enough voltage and current, the larger the speaker impedance in ohms, the smaller the output power.
