Enable your project to hear using this microphone module capable of detecting human-frequency sounds from 20Hz to 20kHz. To enhance the delicate microphone signal, the MAX4466 operating amplifier is used, designed specifically for amplification of the signal from a source such as a microphone. Removes the background noise and leaves a clear and clean signal, ie sound. With the potentiometer on the board, you can easily adjust the microphone sensitivity (boost level) of 25x to 125x.

This module is great for all projects that require voice input, and with FFT you will easily create sound-responsive projects. Use "cleaner" and more stable power source, let's say 3.3V pin from Arduino. The output from this module will be on the half-voltage at the input when there is no impulse on the microphone.

• Input voltage: 1.8V - 5.0V
• Small power output, for headphones or ADC
• Dimensions: 13.0mm x 25.0mm
