The GY-MAX4466 is a microphone amplifier module based on the MAX4466 audio amplifier with especially nice sound and low background noise. Moreover, is the connection very simple and it has additionally a 20-20 kHz microphone. The amplification can be customized with the trimmpoti on the back. It is especially good as a module for voice transformer, audio recorders and other Arduino active projects.
