The ReSpeaker 2-Mic Pi HAT V1.0 Expansion Board is designed to run on a 5V supply and is compatible with Raspberry Pi models 4B, 3B+, and 3B. It features two microphones, and utilizes a Drive IC for efficient operation.
There are two microphones on the shield for sound collection, three APA102 RGB LEDs, one user button and two connectors for application extension. The shield comes with a 2.54mm Grove cable
In addition, a 3.5mm audio jack or XH2.54-2P speaker output can be used for audio output.
With this shield, you can build a more powerful and flexible voice product that integrates Amazon Amazona voice services, Google Assistant, and more.
Note:After plugging in speaker module, the status of RGB LED is not stable; however,the status is normal when testing RGB.
Features
Support the Raspberry Pi 3B
Two microphones (Mic L and Mic R)
Two Grove connectors
One User-defined button
3.5mm audio interface
XH2.54-2P audio output interface
This product includes a number of interface features that enhance its functionality. This includes a button that is connected to GPIO17, and two microphones (labeled LEFT and RIGHT) that are connected to GPIO12 and GPIO13. There are also three APA102 RGB LEDs that are linked to the SPI interface of the Raspberry Pi. Additionally, the Low Power Stereo Codec WM8960 is integrated, along with a 40 pin header that supports the Raspberry Pi Zero, Raspberry Pi 3B and Raspberry Pi 4B. A Micro USB port powers the ReSpeaker 2-Mic Pi HAT, providing enough current for use with the speaker. Other ports include a Grove I2C port, a Grove digital port, an XH2.54-2P SPEAKER OUT port for connecting speakers, and a 3.5mm audio jack for headphones or speakers with a 3.5mm audio plug.
Note:The experiment is done with Raspberry Pi 3B. Yet other versions of Raspberry Pi may not be compatible.
