Description
reSpeaker Flex XVF3800 Linear-4 with XIAO ESP32S3 is an advanced microphone array module designed for robotics, embedded systems, and interactive HMI applications. The device is based on the XMOS XVF3800 processor, which provides high-quality real-time audio signal processing. Thanks to built-in AI algorithms such as noise suppression (NS), acoustic echo cancellation (AEC), and beamforming, the module significantly improves captured audio quality. The split-design architecture separates the processing unit from the microphone array, enabling flexible placement in robotic systems and space-constrained devices.
The version with XIAO ESP32S3 enables direct integration with MCU ecosystems such as Arduino and ESPHome, allowing rapid deployment of voice-based projects. Support for both USB and I2S modes ensures broad compatibility with computers, Raspberry Pi, NVIDIA Jetson, and microcontrollers. The 4-microphone array enables precise sound capture within a 180° field of view, making it ideal for front-facing applications such as information kiosks or control panels.
The system offers a voice capture range of up to 5 meters, enabling convenient voice control in larger spaces without the need to approach the device. Thanks to DoA (Direction of Arrival) technology, it can determine the direction of the sound source, improving interaction precision in robotics and AI systems. The module is designed for professional applications, offering high resistance to interference and stable operation even in challenging acoustic environments. With built-in interfaces and DFU support, firmware updates and device customization are easy to perform. The reSpeaker Flex XVF3800 Linear-4 provides a complete solution for projects requiring advanced voice recognition and audio processing.
