Seeed 103030216 ReSpeaker 4 Mic Array for Raspberry Pi Voice Assistant

The ReSpeaker 4-Mic Array is a Raspberry Pi expansion board that features quad analog microphones and is designed for AI and voice applications. With this board you can design and build more powerful and flexible voice and audio projects that integrate Amazon Alexa Voice Service, Google Assistant, etc.

Differing from the ReSpeaker 2-Mics Pi HAT, this board is based around the AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. An additional feature is the 12x programmable RGB LED ring that gives you the ability to do such things as Voice Activity Detection (VAD), estimation of Direction of Arrival (DOA) and indicate the direction via the LED ring, just like Amazon Echo or Google Home.

• 4x Analog microphones
• 12x Programmable RGB LEDs
• 2x Grove interfaces
• 3m Voice capture distance
• Supports Raspberry Pi Zero, 1 B+, 2 B and 3 B

Note: 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.
