Overview】
Dual microphone array for far-field voice capture: 2 high-performance digital microphones capture and extract far-field voice and speech (up to 3 meters) even in noisy environments because it uses two microphone inputs to eliminate point noise.
[] Board-Hybrid AI NLU Algorithm: The kit is powered by the XMOS XU-316 A1 acoustic audio chip and includes natural language understanding algorithms for interference cancellation (IC), echo cancellation, noise suppression, voice-to-noise ratio (VNR) and automatic gain control (AGC) for high-quality voice capture.
[] Embrace open source: The board is compatible with popular hardware platforms (XIAO ESP32S3 (Sense), Adafruit QT Py) through 12S, and is compatible with Raspberry Pi, PC through US8 (audio class 2.0 (UAC2)).
[] Onboard RGB LED: The board features a programmable WS2812 RGB LED, which supports custom effects and provides a visual interface for your application.
[] External power supply support: The board supports external 5V power supply and can be flexibly applied to different scenarios.
[] DFU customized development: The board supports customized component updates through DFU-Util.
