The ReSpeaker 4-Mic Array for the Raspberry Pi is a quad-microphone expansion board designed for AI and voice applications. Build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant and more!

In contrast to the 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. In addition, this 4-Mics version provides a super cool LED ring, which contains 12 APA102 programmable LEDs.

With 4 microphones and the LED ring, the Raspberry Pi has the ability to do VAD (Voice Activity Detection), estimate DOA (Direction of Arrival) and show the direction via the LED ring, just like Amazon Echo or Google Home.


  • Raspberry Pi NOT included
  • There are no any audio output interfaces on ReSpeaker 4-Mic Array for Raspberry Pi. It is only for voice capture. You could use the headphone jack on Raspberry Pi for audio output.
