Package Included
- 1 pcs x GY-MAX4466 electret microphone amplifier MAX4466 adjustable amplifier module

Description:
- This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT.
- You can set the gain from 25x to 125x. That's down to be about 200mVpp (for a normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC.
- connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the "quietest" supply available (on an Arduino, this would be the 3.3V supply).
- The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volt (it is DC coupled).
