seeed studio reSpeaker XVF3800 4-Mic Array with XIAO ESP32S3 and Case

• Ready for Enclosed Prototyping: The included case reduces enclosure, mounting and assembly work, so you can focus on validating the voice experience instead of building the mechanical package first.
• Onboard Voice Processing: XVF3800 performs AEC, beamforming, de-reverberation, DoA, VAD, AGC and noise suppression before audio reaches your application, helping reduce downstream audio preprocessing.
• 360° Far-Field Voice Capture: Four MEMS microphones in a circular array support speech pickup from different directions at distances up to 5 m, so users do not need to speak toward one fixed microphone position.
• XIAO ESP32S3 for Connected Voice: The pre-soldered XIAO ESP32S3 adds Wi-Fi, Bluetooth Low Energy and MCU-side control for local wake-word projects, smart-home voice interfaces and custom embedded applications.
• Firmware Options: Ships with Standard I2S firmware for XIAO ESP32S3 and is not a USB audio device by default; switch to USB firmware for host audio or use dedicated 48 kHz HA I2S firmware for Home Assistant and ESPHome Voice; configurations are separate.
