Built on a compact footprint, this module is specifically designed for advanced audio and voice recognition applications. With its inherent low-noise and high Signal-to-Noise Ratio (SNR) attributes, it offers crystal-clear audio capture even in challenging environments. Its compatibility with the I2S interface, a standard used for transmitting digital audio between devices, ensures that it can be integrated into a diverse range of audio processing setups. The <strong>INMP441 microphone module </strong>is an invaluable component for developers looking to incorporate superior audio input capabilities into their projects.</p><p class="text-align-justify" style="margin: 6px 0px 10px; text-align: justify; font-size: 16px; line-height: 30px;"> </p><h3 class="text-align-justify" style="font-family: Montserrat, serif; line-height: 28px; color: rgb(17, 17, 17); margin-top: 11.5px; margin-bottom: 11.5px; font-size: 18px; text-align: justify;"><strong>INMP441 Pinout</strong></h3><p style="margin: 6px 0px 10px; text-align: justify; font-size: 16px; line-height: 30px;">The INMP441 microphone modules have six pins, three on each side as shown in the above pinout image.
