Description: Description Raspi Voice HAT Dual Microphone Expansion Board For AI Voice Applications For Raspberry Pi 4B Overview: Raspi Voice HAT is a dual-microphone expansion board for Raspberry Pi specially designed for AI and voice applications. Now you can build a more powerful and flexible voice product that integrates devices for Amazon Amazona voice service, Google Assistant, Baidu AI, etc. The board is an audio module designed based on that for Raspberry Pi. It uses the WM8960 low-power stereo codec, which is controlled by the I2C interface, and the audio is transmitted through the I2S interface. There are two microphones on both sides of the circuit board to collect sound. It also provides 12 APA102 RGB LEDs and an onboard speaker, and provides a user button and an I2C interface for expanding applications. In addition, the on-board 3.5mm audio jack or 2.0 speaker output for JST can be used for audio output, and music can be played through an external headset, and it can also be played with an external speaker through the dual-channel speaker interface. There is a high-quality MEMS silicon microphone on the left and right sides of the board, which can record in stereo.
