MSM261S4030H0 I2S Microphone Module

Product detailed description

The MSM261S4030H0 is a high-quality digital MEMS microphone module with an I2S interface, designed for applications requiring reliable audio transmission with low distortion and a wide dynamic range. Thanks to its omnidirectional characteristic and high resistance to acoustic pressure (up to 140 dB SPL), it is ideal for voice assistants, sound recording, speech recognition or other audio systems. The module uses a 1×6P connector with a 2.54 mm pitch for easy connection and provides a stable digital output without the need for analogue processing.
