Seeed’s ReSpeaker 4-MicsLinear Array Kit for Raspberry Pi is an extension board, aka HAT designed for Raspberry Pi. It's a linear microphone array kit, comes with four microphones and designed for AI and voice applications. That means you can build a more powerful and flexible voice product with Raspberry Pi which can integrate Amazon Alexa Voice Service, Google Assistant, and so on.
ReSpeaker 4-Mic Linear Array Kit for Raspberry Pi consists of two boards, one is voice accessory HAT, another is four microphones linear array.
ReSpeaker 4-Mic Linear Array Kit for Raspberry Pi support 8 input & 8 output channels in the Raspbian system. The first 6 input channels for microphone recording(only first 4 input channels are valid capture data), the rest of the 2 input channels are echo channels of playback. The first 2 output channels for playing, the rest of the 6 output channels are dummy.
Features
2 ADC chips and 1 DAC chip
8 input and 8 output channels
Four microphones array
Grove support
Compatible with Raspberry Pi 40-pin headers
Headset and speaker voice output
Compatible with Raspberry Pi 4
