## Description

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. Specifications Microphone – MSM261S4030H0 MEMS (omnidirectional, bottom-ported) Output – 24-bit I2S digital audio Sensitivity – −26 dBFS @ 1kHz, 1Pa Signal-to-Noise Ratio – 57 dB (A-weighted, 20kHz bandwidth) Max Sound Level – 140 dB SPL Input Voltage – 3.3V ± 0.2V DC Input Current – >1mA Operating Temperature – −30°C to +85°C On-Board LED – SK9822 RGB LED with two-wire control Connector – 16-pin 2.54mm Dupont header Dimensions – 15.2 × 9.1mm Ideal For Digital audio capture and voice recognition projects AI and machine learning audio applications Sipeed MAIX and other I2S-compatible microcontrollers DSP and embedded audio processing Package Contents 1× I2S Microphone Module Resources Documentation & Downloads
