Use 1.8-12 v dc output of the power adapter/battery/charging etc
all can treasure.Will two dc power cord is connected to the amplifier
board
2 p power source port, the positive line to VCC, negative to GND,
the connection is important to make clear is negative, not blindly wiring,
if meet the could
seize power amplifier board.
4. Play music
Put through power supply, amplifier board into working state
