Using Manual
This product is connected to 5V / 20W (W), and the maximum power of peripheral hardware processing can be configured to reach 20W: power supply voltage DC DC voltage 4.9-5V, current 1.6A-2A. It should be reminded that if the power of the power supply and the speaker are not well-matched, and the level of the audio source fails to meet the requirements, the power will naturally not reach. An anti-reverse diode IN4007 is added to the power line. If it is reversed, the board will not be damaged in a short time. After you will connect the wire, remove this diode because the voltage will drop 0.7V after soldering 4007, which will affect the voltage
