ReSpeaker Flex XVF3800 Circular 4-Mic AI Microphone Array, with XIAO ESP32S3, USB/I2S for Robotics Embodied AI

ReSpeaker Flex XVF3800 Circular 4-Mic AI Microphone Array, with XIAO ESP32S3, USB/I2S for Robotics Embodied AI Description

A versatile 4-mic array for robots and embodied AI applications like signage. Separates the core processing board from the microphone array board via a flexible FPC cable, enabling easy integration in space-constrained robotics and embedded applications.
Powered by XMOS XVF3800, it features -board AI acoustic algorithms for better sound quality. Features AEC, multi-beamforming, de-reverberation, DoA, dynamic noise suppression, AGC, delivering stable and reliable voice capture performance.
With a split design, and 4-mic circular array for 360 spatial pickup, come with factory-installed I2S firmware for MCU integration, it supports both dual modes(I2S/USB). In robotics applications, the circular array can be mounted the robot's for omnidirectional voice capture. Support DFU mode for users to the firmware.
XIAO ESP32S3 Pre-Soldered: pre-soldered XIAO ESP32S3, enabling native support for ecosystems such as ESPHome and Home Assistant. This allows developers to easily extend applications into home scenarios and beyond.
The acoustic are positioned the back side of the mic array board, reducing interference from front-facing components. This design also allows the microphones to be placed closer to the sound source or device surface, maximizing voice pickup performance.

Plug-and- via USB: A standard USB interface enables quick connection to devices such as for Raspberry Pi, for for Jetson, and PCs running Windows, Linux, or for macOS, no drivers or complex setup required.
With far-field voice capture to 5 meters and the circular 4-microphone array supporting precise Direction of Arrival (DoA) detection, the reSpeaker Flex delivers reliable voice capture and accurate sound source localization for interactive and voice-driven applications.
