## Description

6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board

## Features

- Application: MAX4466 microphone breakout is suitable for voice converters, audio recording and sampling, and audio response projects using FFT; On the back, there is a small trimmer pot to adjust the gain; You can set the gain from 25x to 125x
- Parameters: power supply voltage: +2.4V to +5.5V (can be compatible with STM, 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: <24μA; Gain bandwidth: 600kHz
- 20-20KHz electret microphone soldered on: 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
- Easy to use: connect GND to ground, VCC to 2.4-5VDC; For the good performance, use the 'quietest' supply available (this would be the 3.3V supply)
- Power supply noise rejection function: the amplifier has good power supply noise rejection

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!  See review for pre-emphasis circuit mods
*by N***. on March 6, 2025*

Sounds great, works well. I modified the circuit to provide a high-pass "pre-emphasis" for use with an AM transmitter. Circuit below:

### ⭐⭐⭐⭐⭐ Great for the price
*by K***J on November 12, 2024*

Wanted a voice activation solution outside having to come up with a Java solution in Android, but didn't have enough resources on ESP32C3 to handle voice recognition well. Settled on a "whistle trigger" (using Goertzel constants; frequencies matching whistling on a b-flat scale triggers current on different I/O pins) instead. This worked out reasonably well, though I was foiled again by ceiling fans. Struggled to get consistent readings; eventually realized I had a ceiling fan pointed directly at the microphone; things were fine after turning off the fan.

### ⭐⭐⭐⭐ Works, but you may be better with an I2S or I2C Mic
*by J***A on May 24, 2024*

The product overall is a very nice one - I wish the headers were pre-soldered, but that's not a dealbreaker. Dealing with Analog Signals, especially if you're utilizing something like CircuitPython is a bit more trouble than it's worth. You can grab I2S Microphones for a similar price and quantity for a much smoother experience.
