Pin
KEY : Button control terminal (4 button functions, additional resistance required)
MUTE: Mute control terminal (output high level 3.3V when muting, output low level during playback)
VCC: Positive 5V power supply (Lithium battery 3.7V power supply requires short circuit diode)
GND: negative power supply
L: Left channel output
R: Right channel output
Feature:
Control terminal: used to control the power amplifier board. When muting, MUTE outputs a high level of 3.3V, and outputs a low level during playback.
