#ReSpeaker 4 Mic Array
|
||||
|
||||
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.
|
||||
|
||||
The board is developed based on AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. Besides, it 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.
|
||||
|
||||
* MIC: 4 Microphones on the corners of the square board
|
||||
* RGB LED: 12 APA102 RGB LEDs, connected to SPI interface
|
||||
* AC108: a 4-channels ADC
|
||||
* Raspberry Pi 40-Pin Headers: support Raspberry Pi Zero, Raspberry Pi 1 B+, Raspberry Pi 2 B and Raspberry Pi 3 B
|
||||
* I2C: Grove I2C port, connected to I2C-1
|
||||
* GP12: Grove digital port, connected to GPIO12 & GPIO13

#ReSpeaker 4 Mic Linear Array
|
||||
|
||||
This HAT comes with 4 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. It consists of two boards, one is voice accessory HAT, another is four microphones linear array. It supports 8 input & 8 output channels in Raspbian system. The first 6 input channel for microphone recording(only first 4 input channels are valid capture data), rest of 2 input channel are echo channel of playback. The first 2 output channel for playing, rest of 6 output channel are dummy.
|
||||
|
||||
* MIC: 4 Microphones
|
||||
* RGB LED: 12 APA102 RGB LEDs, connected to SPI interface
|
||||
* AC108: 2 4-channels ADC
|
||||
* AC101: a 2-channels DAC
|
||||
* Raspberry Pi 40-Pin Headers: support Raspberry Pi Zero, Raspberry Pi 1 B+, Raspberry Pi 2 B and Raspberry Pi 3 B
|
||||
* I2C: Grove I2C port, connected to I2C-1
|
||||
* GP12: Grove digital port, connected to GPIO12 & GPIO13
|
||||
* JST 2.0 SPEAKER OUT: for connecting speaker with JST 2.0 connector
|
||||
* 3.5mm AUDIO JACK: for connecting headphone or speaker with 3.5mm Audio Plug
