## Description

A 6+1 MEMS microphone array built around seven MSM261S4030H0 high-sensitivity digital silicon microphones. Designed for advanced audio applications including noise suppression, echo cancellation, reverb reduction, and sound source localisation. The array outputs raw digital audio over I2S, eliminating the need for an external codec. This fully digital signal path reduces design complexity while improving noise immunity. An onboard ring of 12 SK9822 RGB LEDs provides visual feedback with 256-level colour and 32-level brightness control. Key Features 7-Microphone Array – Six omnidirectional MEMS microphones plus one centre microphone for beamforming Digital I2S Output – 24-bit audio direct to DSP or MCU, no external codec required High Sensitivity – −26 dBFS @ 1kHz, 1Pa with 57dB signal-to-noise ratio (A-weighted) 140 dB SPL – Handles high sound pressure levels without distortion 12 RGB LEDs – SK9822 ring array with 256-level colour and 32-level brightness Two-Wire LED Control – Synchronous dual-lane interface for positive or negative output RGB Specifications Microphone Chip – MSM261S4030H0 (omnidirectional, bottom-ported, I2S digital output) Audio Output – I2S digital Sound Pressure Level – 140 dB SPL Sensitivity – −26 dBFS @ 1kHz, 1Pa Signal-to-Noise Ratio – 57dB (20kHz bandwidth, A-weighted) LED Current – 20mA per colour, 60mA total at full brightness LED Viewing Angle – 120° Input Voltage – 3.3V ±0.2V DC Input Current – >750mA (full brightness) Dimensions – 78.1 × 88.8mm Connectors – 2×5P 2.54mm header and 10P 0.5mm FPC Operating Temperature – −30°C to 85°C Ideal For Voice assistant and smart speaker projects Sound source localisation and beamforming Noise and echo suppression applications Far-field voice recognition systems Package Contents 1× 6+1 Microphone Array Resources Datasheet (PDF) Product Data (RAR)
