Product Details
This digital I2S MEMS microphone is a great match for microcontrollers with I2S audio outputs, such as the ESP32. Unlike traditional analog microphones, it offers low noise, high sensitivity, and excellent reliability. These features make it perfect for various projects, including voice recognition, recording, AI learning, and Bluetooth audio transmission. The module uses a surface - mount MEMS I2S microphone sensor with a top port and no components on the bottom, allowing for easy integration into different applications. DFRobot also provides an Arduino library for this product, enabling users to quickly start working with the ESP32. It has several great features like small size, low power consumption, high - performance, I2S digital output with low noise, a highly reliable MEMS sensor, and support for an Arduino library on ESP32. Its applications range from voice recognition to smart home audio projects. The specifications include an operating voltage of DC 3.3V, MEMS packaging process, omnidirectional direction, I2S data port, 140dB sound pressure level, 59dB signal - to - noise ratio, and dimensions of 11mm×16mm (0.43×0.63'). There are also various documents available, such as the product wiki, 3D and 2D CAD models, and schematics diagrams. The shipping list includes one Fermion I2S MEMS microphone and one 6P black single - row pin connector.
Using this Fermion I2S MEMS microphone is quite easy. First, connect it to your ESP32 or other compatible microcontroller with I2S audio output. Thanks to the Arduino library provided by DFRobot, you can quickly start programming and using it. When using it for projects like voice recognition or recording, make sure the environment is not too noisy to get the best results. As for maintenance, keep it away from moisture and dust. Don't apply excessive force to the microphone or its connectors. If you need more information, you can refer to the product wiki. And remember, the operating voltage is DC 3.3V, so always use the correct power source.
