Reference Design - Soundskrit Horizon Demo Platform

The Soundskrit Horizon Demo Platform helps product makers discover how directional microphones can be integrated into various end products. Using the NXP MIMXRT1062 MCU, this design is compatible with Audio Weaver and features a built-in 5-mic array with adjustable configurations. Connected over USB, the kit appears as a soundcard, allowing easy recording of any of the microphones or processed signals. With this platform, audio layouts leveraging directional microphones can be easily created and tuned, switching between microphone pairs based on the use case. Convenient mounting hardware is included for affixing the demo platform to the bezel of a notebook computer, to test microphone configurations in specific use cases.
