I2S Microphone Module
A compact digital MEMS microphone module based on the MSM261S4030H0 chip, providing 24-bit I2S digital audio output. The built-in I2S interface connects directly to DSPs and microcontrollers without requiring an external codec, simplifying audio capture designs. An on-board SK9822 RGB LED provides visual feedback with two-wire colour control.
The omnidirectional, bottom-ported microphone delivers high sensitivity with a 140 dB SPL acoustic overload point and 57 dB signal-to-noise ratio, making it well-suited for voice capture, audio processing, and AI applications.
