The GY-MAX4466 Electret Microphone Sensor Module pairs an electret microphone capsule with the MAX4466 amplifier IC, providing 20dB base gain with a 600kHz gain bandwidth product and 125dB high AVOL (at 100kΩ load), operating from 2.4V to 5.5V at just 24µA input current, compatible with Arduino and other microcontroller boards. Unlike fixed-gain sound sensors, the max4466 microphone sensor’s standout feature is its onboard adjustable gain trimmer potentiometer, letting users physically dial amplification up or down to match the loudness of their environment.
The microphone amplifier max4466 converts sound waves picked up by the electret capsule into an amplified analog voltage output, readable directly through an Arduino analog pin — louder sounds produce larger voltage swings, while the trimmer’s gain adjustment determines how sensitive this response is to quiet versus loud input. This max4466 sound sensor’s gain control is particularly useful for projects moving between noisy and quiet environments, since fixed-gain alternatives often saturate too easily in loud settings or miss quiet sounds entirely.
As a max4466 mic module, this sensor is designed for sound level detection, clap triggers, and basic audio visualization rather than high-fidelity audio recording, since the analog output isn’t intended for capturing detailed voice or music quality. Available from StemVolt, Ideal for enthusiast and project developers, this GY-MAX4466 electret microphone sensor module with gain control, Its perfect for audio detection, sound analysis, and embedded projects requiring adjustable microphone sensitivity.
