Connect the speakersThe speakers at both ends of the wire at the end of the line are connected to the audio amplifier board port output, the left channel sound is connected to the LOUT port of the power amplifier board, and the cathode is connected to GND.The positive line power amplifier is correctly wired on the ROUTE port, and the cathode is connected to GND.2. Connect audio sourceUse a 2-core audio cable, connect to the input of the 3p audio amplifier board, and connect the other end of the audio cable plug to the sound source (for example, computer, mobile phone, MP3, DVD, etc.)3. Connect the power cordEveryone can cherish the 1.8-12v DC output using power supply/battery/charging adapter, etc. Connect the two DC power cables to the 2p power port on the edge of the amplifier, with the positive pole to VCC and the negative pole to GND,It is important to figure out that the connection is negative, not blindly wiring. If they meet, they may hold the power amplifier board.4. Play musicTurn on the power, the amplifier board is in working condition; you can adjust the volume knob according to your preferences.Note:There may be slight size deviations due to manual measurement, different measuring methods and tools.The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor.
