INMP441 Omnidirectional MEMS Microphone Module with I2S Interface, Low Power, Compatible with ESP32

The INMP441 is a high-performance, low-power MEMS microphone module with a digital output and omnidirectional pickup pattern. Each module connects at the bottom edge and integrates a complete signal chain, including the MEMS sensor, signal conditioning, analogue-to-digital conversion, anti-aliasing filtering and power management, all within a compact unit. The 24-bit I2S interface follows industry standards, allowing the microphone to connect directly to digital processors such as DSPs and microcontrollers without requiring a separate audio codec in the system. Designed for straightforward integration, the module is compatible with ESP32 development boards and other I2S-capable controllers. The omnidirectional response captures sound evenly from all directions, making it suitable for voice capture, audio recording and acoustic sensing projects. Installation is simple, and the digital output helps maintain clean signal transfer over short distances. This pack contains six INMP441 modules, providing multiple channels for array-based recording or spare units for prototyping and experimentation. Each module is ready to use with standard I2S wiring, helping you move quickly from setup to functional audio capture.
