Adafruit I2S 3W Stereo Speaker Bonnet for Raspberry Pi (Mini Kit)

Get ready to amplify your Raspberry Pi audio experience with this compact 3W Stereo Amplifier Bonnet! Although it’s not quite large enough to be classified as an official HAT, we’ve called it a "bonnet" to match its size. It’s designed to fit perfectly on any Raspberry Pi with a 2x20 connector, including models like A+, B+, Zero, Pi 2, Pi 3, Pi 4, and more. We’ve tested it with both Raspbian and Retropie to ensure top performance.

This bonnet uses the I2S digital sound standard, delivering crisp, clear audio with no static interference like you might hear from the headphone jack. Setting it up is a breeze—just plug in any 4Ω to 8Ω speakers (up to 3W), run the included installer script on your Raspberry Pi, reboot, and you’re ready to rock.

Each order includes a fully assembled and tested PCB, along with two extra terminal blocks. No soldering is required if you use our 3W speaker set—simply plug and play. You can either connect our included speakers directly via the JST jack or solder on the terminal blocks to use your own speakers (such as our 4Ω 3W or 8Ω 1W options). You can even use a surface transducer if you prefer!

Our handy tutorial will guide you through setup, and you'll be jamming out in just 15 minutes.

Make sure you have a strong 5V power supply, especially when using the 3W 4Ω speakers. We recommend a 2.4A power plug for optimal performance. Note that the Raspberry Pi and speakers are not included, and the terminal blocks in your order may be either blue or black.
