Two-Microphone Pi HAT Extension Board

Add a two-microphone audio input to a compatible Raspberry Pi project with a ReSpeaker 2-Mics Pi HAT.

✅ Bring two microphone inputs to the build - The HAT provides the described audio-input arrangement for your application.

✅ Use the Pi as the project host - The add-on format is intended for the listed Raspberry Pi board family.

Build the voice workflow in software

A voice project needs audio capture before it can recognise a command or record a sound. This board supplies the input stage while the host application determines what happens to that audio.

Confirm the exact V2.0 board, GPIO fit and driver support before connecting it. The HAT is not a finished voice assistant or a guarantee of speech recognition; software, suitable power and the Raspberry Pi are separate parts of the project.
