## Overview

This 6-piece MAX4466 Electret Microphone Amplifier Module set features adjustable gain from 25x to 125x, operates on a wide 2.4-5.5V range compatible with popular development boards, and boasts a high 112dB power supply noise rejection for clean audio input. Each board includes a built-in 20Hz-20kHz electret microphone, making it ideal for voice converters, audio recording, and FFT-based audio projects.

## Description

desertcart.com: 6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board : Industrial & Scientific

Review: Great for the price - 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.
Review: Works great! See review for pre-emphasis circuit mods - Sounds great, works well. I modified the circuit to provide a high-pass "pre-emphasis" for use with an AM transmitter. Circuit below

## 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

### ⭐⭐⭐⭐ Analog
*by K***K on June 20, 2025*

Good purchase for the price. Still working with it. This is an analog output device. If you want to learn about analog, this is a very good option. Things like Analog Digital Conversion, physical filtering, signal processing, etc., can be elusive for most of the devices you get in a sensor kit. However, this is the "stick shift" of input devices. The onus is back on you. Rather than the pre-digitized signals you might get elsewhere, you have to figure out what to do with that wavy signal. Have fun
