Each board includes a built-in 20Hz-20kHz electret microphone, making it ideal for voice converters, audio recording, and FFT-based audio projects. ## Description Product description 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: Amplified electric condenser mic’s - Received In brand new perfect condition. Well packaged items. These amplified condenser electric microphones didn’t work well for my project that I was working on. With that said, it’s probably me more than the product. I’m sure they could work ok on other devices. They are pretty nice . It’s amazing that you can adjust the mic gain with a very small pot located on the bottom of the board. Maybe I’ll have better luck on some future projects. Good luck! ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #59,344 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #11 in Audio Amplifiers | | Customer Reviews | 4.2 out of 5 stars 160 Reviews | ## Images ![6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board - Image 1](https://m.media-amazon.com/images/I/81d-hbs72RL.jpg) ![6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board - Image 2](https://m.media-amazon.com/images/I/71ddRTUapzL.jpg) ![6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board - Image 3](https://m.media-amazon.com/images/I/71C4kJcHtFL.jpg) ![6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board - Image 4](https://m.media-amazon.com/images/I/71MnOOC1bsL.jpg) ![6 Pieces Electret Microphone Amplifier Module MAX4466 Adjustable Gain Blue Breakout Board - Image 5](https://m.media-amazon.com/images/I/71b62sI8EGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.

I modified the circuit to provide a high-pass "pre-emphasis" for use with an AM transmitter.
