Wiring instructions:(Please pick twouse4Ω3-5WFull-range speaker)
1, The white socket GND on the circuit board is connected to the negative pole of the 5V power supply, and +5V is connected to the positive pole of the 5V power supply;
2, The white carrier L- connects to the left speaker-pole, and L+ connects to the left speaker + pole;
3, The white seat R- connects to the right speaker-pole, R+ connects to the right speaker + pole;
Note: The working voltage is 3.7-5.0V, the current is about 700 mA when connected to a 4 ohm 3W speaker, and the current is about 1400 mA when connected to two 4 ohm 3W speakers. If the current is not enough, automatic music change or remote control failure will occur.(If you have this problem, please improve your power supply); Excessive voltage will burn the power amplifier IC and the main chip(Be careful not to connect reverse current and do not exceed the limit voltage, and do not use alternating current).
