MAX 4466 Electret Microphone Amplifier with Adjustable Gain – Audio Sensor Module

• IC: MAX4466 Low-noise Op-amp
• Microphone Type: Electret condenser microphone
• Operating Voltage: 2.4V – 5.5V DC
• Output: Analog audio signal
• Adjustable Gain: 25x to 125x (via onboard potentiometer)
• Board Size: ~20mm × 15mm
• Mounting: 2 × fixing holes

Ideal for voice recognition systems, audio recording, sound level detection, speech-activated devices, and DIY electronics projects requiring microphone input.

Rotate the onboard potentiometer to adjust gain. Connect VCC, GND, and OUT pins to your microcontroller or ADC input. Ensure stable 3.3V or 5V supply for clean audio performance.
