Home Arduino Module Sensor Chips About Us Features 1.Adopting PAM8403 chip, it is a 3 watt class D audio power amplifier 1C, featuring low harmonic distortion and low noise crosstalk. 2. This dual-channel digital amplifier board, using the 3P audio terminal input, the input voltage is DC5V. 3. 50K volume adjustment relay on board, can do the amplifier power on, off, but also free to adjust the volume. 4. This amplifier also has a dual-channel audio output, power 2 * 3W, small power office speakers can be directly with. 5. The use of high-quality components, so that its sound playback to get a better sound quality; at the same time it is much better than the efficiency of the Class A amplifier, which extends the battery life, is the ideal choice for portable equipment. 6. On-board volume potentiometer, on-board switch and volume adjustment potentiometer, you can freely adjust the volume level and switch the power supply. Turn clockwise to turn on the power and increase the volume, turn counterclockwise to decrease the volume and turn off the power.
