ReSpeaker 2 Mics pHAT

ReSpeaker 2-Mics Pi HAT V2.0 is a dual-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 TLV320AIC3104, a low power stereo codec. There are 2 microphones on both sides of the board for collecting sounds and it also provides 3 APA102 RGB LEDs, 1 User Button and 2 on-board Grove interfaces for expanding your applications. What is more, 3.5mm Audio Jack or JST 2.0 Speaker Out are both available for audio output.

For specific instructions on adapting the HAT to be compatible with the BeagleY-AI, visit this Github or this hackster project.
