Microphone Amplifier Module GY-MAX4466 Breakout Sensor with Adjustable Breakout Board for Arduino
Product Description:3pcs Electret Microphone Amplifier MAX4466 Module, Microphone Amplifier Module, GY-MAX4466 Breakout Sensor, with Adjustable Gain Breakout Board for ArduinoThe MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier. Add an ear to your project with this well-designed which has excellent power supply noise rejection.On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away).Using introduction:Connect GND to ground, VCC to 2.4-5VDC.The audio waveform will come out of the OUT pin.The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled).If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device.If you're connecting to an audio amplifier that has differential inputs or
