AJMRTC MH-ET LIVE INMP441 MEMS microphone module is a high-precision digital audio sensor board built with INMP441 omnidirectional MEMS microphone. It uses standard I2S digital audio interface to output 24-bit audio data directly to ESP32 and other I2S-support microcontrollers, removing analog noise issues and extra ADC circuits. With 61dBA high signal-to-noise ratio, -26dBFS sensitivity and stable 60Hz to 15kHz frequency response, it delivers clear and natural voice recording. It only consumes 1.4mA working current and accepts 1.8V to 3.3V input voltage, ideal for low-power IoT equipment. The ultra-small PCB saves space inside your embedded device. Widely used for voice recognition, voice wake-up, ambient sound detection, smart home and DIY audio projects. Simple pin definition enables fast connection and quick development for electronic hobbyists.
