LM386 Audio Amplifier Module

This LM386 module is a low-cost audio amplifier module with the famous LM386 amplifier IC on it. The gain of the circuit is about 200 that means the output can be amplified 200 times. The operating voltage of the module is from 5V to12V. It also has an on-board power indicator LED and a 10k potentiometer which can be used to adjust the volume (gain) of the output audio signal.

Specifications
