The 386AMP audio amplifier module uses the National Semiconductor LM386 audio power amplifier chip. It has 20 voltage gain.
With a 6V power supply, it has a static power consumption of only 24mW, the module is suitable for battery-powered applications. The 386AMP audio amplifier can be connected to MIC or acoustic sensor module, after the sound is amplified it is passed to the speaker. It is ideal for robot human-machine voice interaction and sound amplification.
