{"title":"6+1 Microphone Array","handle":"6-1-microphone-array","url":"/products/6-1-microphone-array","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.\n\nThe 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.\n\nKey Features\n\n\n7-Microphone Array – Six omnidirectional MEMS microphones plus one centre microphone for beamforming\n\nDigital I2S Output – 24-bit audio direct to DSP or MCU, no external codec required\n\nHigh Sensitivity – −26 dBFS @ 1kHz, 1Pa with 57dB signal-to-noise ratio (A-weighted)\n\n140 dB SPL – Handles high sound pressure levels without distortion\n\n12 RGB LEDs – SK9822 ring array with 256-level colour and 32-level brightness\n\nTwo-Wire LED Control – Synchronous dual-lane interface for positive or negative output RGB\n\n\nSpecifications\n\n\nMicrophone Chip – MSM261S4030H0 (omnidirectional, bottom-ported, I2S digital output)\n\nAudio Output – I2S digital\n\nSound Pressure Level – 140 dB SPL\n\nSensitivity – −26 dBFS @ 1kHz, 1Pa\n\nSignal-to-Noise Ratio – 57dB (20kHz bandwidth, A-weighted)\n\nLED Current – 20mA per colour, 60mA total at full brightness\n\nLED Viewing Angle – 120°\n\nInput Voltage – 3.3V ±0.2V DC\n\nInput Current – >750mA (full brightness)\n\nDimensions – 78.1 × 88.8mm\n\nConnectors – 2×5P 2.54mm header and 10P 0.5mm FPC\n\nOperating Temperature – −30°C to 85°C\n\n\nIdeal For\n\nVoice assistant and smart speaker projects\nSound source localisation and beamforming\nNoise and echo suppression applications\nFar-field voice recognition systems\n\n\nPackage Contents\n\n1× 6+1 Microphone Array\n\n\nResources\n\nDatasheet (PDF)\nProduct Data (RAR)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2646,"title":"Default Title","sku":"DF-SEN0325","price":27.58,"on_sale":false,"in_stock":true,"available_quantity":49,"option1":"Default Title"}]}
