Product description
INMP441 is a high-performance, low-power MEMS microphone with digital output and omnidirectional pickup pattern. The integrated A/D converter means the signal is delivered as digital data directly from the module. INMP441 features an I2S interface and is mounted on a board. Supplied with pin header (not pre-soldered) for connection to e.g. a breadboard. Suitable for voice control, audio recording, IoT projects, and other sound-based applications.
The board is designed for easy integration in prototyping and development environments and can for example be used together with certain Arduino boards or ESP32 (I2S support required).
