Adafruit Voice Bonnet for Raspberry Pi -Two Speakers + Two Mics

The Adafruit Voice Bonnet gives your Raspberry Pi high-quality audio input and output using the WM8960 I2S codec. With two built-in analog microphones and two 1W speaker outputs, it's designed for voice assistant projects, audio recording, and machine learning applications — all in a compact bonnet form factor.

Simply plug it onto any Raspberry Pi with a 2×20 header (Pi Zero through Pi 4 and beyond) and run the installer script. The microphones and speakers appear as standard audio devices in Linux, so they work with any software. Ferrite beads and filter capacitors on every input and output ensure clean, high-quality audio.
