{"title":"I2S Microphone Module","handle":"i2s-microphone-module","url":"/products/i2s-microphone-module","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.\n\nThe 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.\n\nSpecifications\n\n\nMicrophone – MSM261S4030H0 MEMS (omnidirectional, bottom-ported)\n\nOutput – 24-bit I2S digital audio\n\nSensitivity – −26 dBFS @ 1kHz, 1Pa\n\nSignal-to-Noise Ratio – 57 dB (A-weighted, 20kHz bandwidth)\n\nMax Sound Level – 140 dB SPL\n\nInput Voltage – 3.3V ± 0.2V DC\n\nInput Current – >1mA\n\nOperating Temperature – −30°C to +85°C\n\nOn-Board LED – SK9822 RGB LED with two-wire control\n\nConnector – 16-pin 2.54mm Dupont header\n\nDimensions – 15.2 × 9.1mm\n\n\nIdeal For\n\nDigital audio capture and voice recognition projects\nAI and machine learning audio applications\nSipeed MAIX and other I2S-compatible microcontrollers\nDSP and embedded audio processing\n\n\nPackage Contents\n\n1× I2S Microphone Module\n\n\nResources\n\nDocumentation & Downloads\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4167,"title":"Default Title","sku":"DF-SEN0327","price":6.1,"on_sale":false,"in_stock":true,"available_quantity":278,"option1":"Default Title"}]}
