MSM261S4030H0 I2S Microphone Module

High-Performance I2S Digital Interface: Transmits uncompressed digital audio data directly over an I²S bus, eliminating analog noise interference and avoiding host-side ADC conversion.

Omnidirectional MEMS Acoustic Capsule: Built with a high-sensitivity MSM261S4030H0 MEMS microphone element featuring uniform 360° sound pickup and high signal-to-noise ratio (SNR).

Selectable Left/Right Channel Output: Features a hardware channel configuration pin (L/R) to easily designate left or right audio channels for stereo microphone array configurations.

Low Power Consumption: Operates with minimal current draw, making it an ideal digital audio pickup choice for battery-powered IoT nodes and portable speech processing units.

Ultra-Compact Circular Breakout Board: Streamlined form factor outfitted with standard 0.1'' (2.54 mm) header terminals for simple solderless breadboarding or custom PCB integration.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with gold/tin-plated contact terminals and surface-mount MEMS microphone element.

Technical Specifications:

Operating Voltage: 3.3V DC (3.0V - 3.6V).

Communication Interface: Digital I²S (SCK, WS, SD).

Sensitivity: -26 dBFS.

Color: Black Circular PCB with Silver MEMS Capsule and Gold/Silver Leads.

Usage Advice: Connect VCC (3.3V), GND, SCK (Clock), WS (Word Select), and SD (Data) to I²S-capable microcontrollers like ESP32 or Raspberry Pi; pull the L/R pin low for Left channel or high for Right channel.

Maintenance: Keep the acoustic inlet port clear of solder flux, dust, and liquids; clean surrounding PCB areas gently with a dry microfiber cloth.

Essential High-Fidelity Digital Audio Node: Position as a top-tier digital MEMS microphone for ESP32 voice assistants, smart speaker arrays, local keyword spotting, and edge-AI speech analytics.

Highlight Direct Digital I²S Signal Quality: Emphasize how direct I²S telemetry bypasses analog noise and CPU-intensive analog-to-digital processing for crystal-clear audio stream ingestion.

Recommended Cross-Sell Add-ons: Pair with INMP441 Omnidirectional Microphone Module, MP34DT01 PDM MEMS Microphone Module, Microphone Sound Sensor Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
