6+1 Microphone Array
10 units available with a short lead time.
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
