The ReSpeaker Mic Array can be stacked (connected) right onto the top of ReSpeaker Core to significantly improve the voice interaction experience. It is developed based on the XVSM-2000 Smart Microphone from XMOS. The board integrates 7 PDM microphones to help enhance ReSpeaker's acoustic DSP performance to a much higher level. With the Mic Array attached onto the top of the ReSpeaker Core, ReSpeaker is now able to:
Far-field Voice Capture
Acoustic Source Localization
Acoustic Echo Cancellation
XMOS microcontroller with 16 cores inside
7 high performance digital microphones
Supports Far-field Voice Capture (up to 10m)
Supports Beamforming, Acoustic Source Localization, Nosie Suppression, De-reverberation and Acoustic Echo Cancellation
12 programmable RGB LED indicators
Microphones: ST MP34DT01-M
Sensitivity: -26 dBFS (Omnidirectional)
Acoustic overload point: 120 dBSPL
SNR: 61 dB
Power Supply: 5V DC from Micro USB or expansion header
Dimensions: 70mm (Diameter)
