BulletPoint1 : MAX4466 microphone breakout is suitable for voice converters, audio recording and sampling, and audio response projects using FFT. Support STM Raspberry Pi and other development board motherboards. On the back, there is a small trimmer pot to adjust the gain; You can set the gain from 25x to 125x.
BulletPoint2 : The MAX4466 is a micro power operational amplifier optimized for use as a microphone preamplifier. It is a nice combination of optimized gain bandwidth products and supply current, as well as low voltage operation in an ultra small package.
BulletPoint3 : The MAX4466 has gain stability, requiring only 24μA of supply current to provide a 200kHz gain bandwidth. After decompression, a minimum stable gain of +5V/V can be achieved, and a 600kHz gain bandwidth product is provided.
BulletPoint4 : These amplifiers have rail to rail output, high AVOL, and good power supply noise rejection and common mode rejection ratio, suitable for working in noisy situations.
BulletPoint5 : Comes with a 20-20KHz electret microphone soldered on the board for audio reactive projects; It is recommended to use the FFT driver library, which can take audio input and ' translate' it into frequencies.

How to use:
- 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 it's quiet, the voltage will be a steady VCC/2 volt (it is DC coupled).
- If the audio device requires AC-coupled audio, please place a 100uF capacitor between the output pin and the input of the device.
- If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
- The output pin is not designed to drive speakers, but to drive the smallest in-ear headphones. You need an audio amplifier (such as a 3.7W stereo amplifier).
- If you want to connect the amplifier directly to the speakers or it is connected to a microcontroller pin, no amplifier or decoupling capacitor is needed to connect the OUT pin directly to the microcontroller ADC pin.
- For audio reactive projects, it is recommended to use the FFT driver library, which can take audio input and 'translate' it into frequencies.
Place of Application:
- Widely applied in cellular phones, digital repeater, earphones, hearing aids, microphone preamplifier, portable computers, and voice recognition systems.
