5Pcs GY-MAX4466 Electret Microphone Amplifier MAX4466 Module Adjustable Gain Breakout Board for Kuvaus

Using the MAX4466, an op-amp specifically designed for amplifier, which has excellent power supply noise rejection, and the board comes with a 20-20KHz electret microphone soldered . the back, we include a small trimmer pot to adjust the gain.
Power supply voltage: +2.4V to +5.5V (can be compatible with for STM, for Raspberry Pi and other development board motherboards); Power supply rejection ratio: 112dB; Common mode rejection ratio: 126dB; AVOL: 125dB (RL = 100kΩ) rail-to-rail output; Quiescent power supply current: Less than 24μA; Gain bandwidth: 600kHz. The output is rail-to-rail so if the sounds gets loud, the output can go to 5Vpp!
Applications: This breakout board is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT.
Note:For the best performance, use the "quietest" supply available ( an for , this would be the 3.3V supply); For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.
The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier. They provide an perfect combination of optimized gain-bandwidth products and supply current, as well as low-voltage operation in super packages.

Material: PCB+metal
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 bias of VCC/2 so when its perfectly quiet,
the voltage will be a steady VCC/2 volts (it is coupled).
1.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.
2.If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
3.If you want to connect the amp directly to speakers. If you're connecti
