MAX4466 Electret Microphone Amplifier with Adjustable Gain Module

Overview of this max4466 electret microphone amplifier

Introducing Roboway MAX4466 electret microphone amplifier with Adjustable gain module at best price. This MAX4466 Electret Microphone Amplifier is a compact and high-performance sound detection module that amplifies very low audio signals like voices or ambient sound and making them strong enough for microcontrollers to detect and process.

It is powered by a 3V to 5V power supply and making it compatible with most popular microcontrollers and development boards like Arduino, Raspberry Pi, ESP32, and more. This module gives an analog output signal, which can be easily read and processed using the analog input pins of a microcontroller for real-time audio analysis or sound-based triggering.
