This little module has made a huge difference in my audio projects, and I couldn't be happier with its performance. First and foremost, the sound quality that this microphone amplifier delivers is outstanding. The MAX9814 AGC (Automatic Gain Control) feature ensures that the audio input is automatically adjusted to maintain a consistent, clear output even in environments with varying noise levels. This has been a game-changer for me, as it eliminates the need for constant manual adjustments and guarantees optimal recording quality. The build quality of the module is top-notch. It feels sturdy and well-constructed, which instills confidence in its durability. I've used it extensively in my projects, and it has held up flawlessly, even with repeated use. One aspect that sets this module apart is its compact size. Its small form factor makes it incredibly versatile and easy to integrate into different projects. Whether I'm using it for audio recording, voice recognition, or any other application that requires audio input, the Teyleten Robot MAX9814 module fits perfectly without taking up much space. Installation and setup were a breeze. The module comes with clear and concise instructions, making it a hassle-free experience for both beginners and experienced users. Additionally, the labeled pins and connectors make wiring straightforward and error-free.

In summary, the Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module is an exceptional product that I highly recommend to anyone looking for reliable and high-performance audio solutions. Whether you're a hobbyist tinkering with electronics or a professional in need of a dependable microphone amplifier, this module will not disappoint. Its superb sound quality, robust build, compact design, and user-friendly setup make it an absolute winner in my book. Two thumbs up! Review: A little noisy - Even with a lot of shielding at full gain there is considerable noise. However with the two lower gain settings the noise is considerably reduced. The mic audio sounds clear if a little bassy. Removing the mic and attaching external audio results in clean audio. Again, the lower gain settings are best. Worth getting as long as you don't expect high fidelity. Good for smaller projects. ## Features - The MAX9814 is a low-cost, high-performance microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. - The device features a low-noise front-end amplifier, variable gain amplifier (VGA), output amplifier, microphone bias voltage generator, and AGC control circuit ## Images ![Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module Auto Gain Control Release Ratio Low THD for Arduino 3pcs - Image 1](https://m.media-amazon.com/images/I/71jPqltSVSL.jpg) ![Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module Auto Gain Control Release Ratio Low THD for Arduino 3pcs - Image 2](https://m.media-amazon.com/images/I/71HIAAhTX7L.jpg) ![Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module Auto Gain Control Release Ratio Low THD for Arduino 3pcs - Image 3](https://m.media-amazon.com/images/I/71+8-0DMVzL.jpg) ![Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module Auto Gain Control Release Ratio Low THD for Arduino 3pcs - Image 4](https://m.media-amazon.com/images/I/71+wIbmiezL.jpg) ![Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module Auto Gain Control Release Ratio Low THD for Arduino 3pcs - Image 5](https://m.media-amazon.com/images/I/61BMKFMysKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfect *by T***N on 22 July 2023* I am thrilled with the Teyleten Robot MAX9814 Electret Microphone AGC Amplifier Module!

That said, I tried multiple wiring methods ie. headers with jumpers, breadboard, and directly soldering the wiring to the board and bridging the connection for a 40db output. I tried the 60 and 50 db as well using the other methods but couldn't get an actual usable signal to feed into wled. At times the lights would react but paying close attention would reveal that it was due to signal noise and not audible noise. I would like to believe that I wasn't sold 3 completely nonfunctional parts and that I must've made a mistake. I know now that analog mics are not recommended for wled and have since ordered digital ones but have yet to have a chance to try them. That said, while these are not recommended, they are supposed to be usable with wled so take this review how you want to. I often see other people trash products that work with no problem for me saying that they got 5 or 10 nonfunctional parts so I'll give the benefit of the doubt here and hope if you order them your experience is better than mine.
