ReSpeaker 4-Mic Array for Raspberry Pi is a quad-microphone expansion board for Raspberry Pi designed for AI and voice applications. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on.

 

Different from ReSpeaker 2-Mics Pi HAT, this board is developed based on AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. Besides, this 4-Mics version provides a super cool LED ring, which contains 12 APA102 programmable LEDs. With that 4 microphones and the LED ring, Raspberry Pi would have ability to do VAD(Voice Activity Detection), estimate DOA(Direction of Arrival) and show the direction via LED ring, just like Amazon Echo or Google Home.

 

Note

Please note that the package does not contain Raspberry Pi.

I recommend this product

Pakronics were great, but wont buy seeed product again

Pakronics were great, product shipped next business day with no issue. Australia Post held up delivery 36 hours. Seeed appear to have stopped support ... no presence on their forum or updates to their drivers since mid 2019. Advice is to use OS from 2018

Pakronics®

Thank you for taking time writing your feedback. Can you send us details of technical issue you are facing then we can get seeed engineer clarify. There is no update on driver but it is still being manufacturer so it should have support you need and should function as it suppose to. We will get that sort asap. Please include details of issue and code you are using. Cheers
