NEW PRODUCT – Adafruit Voice Bonnet for Raspberry Pi -Two Speakers + Two Mics
Your Raspberry Pi computer is like an electronic brain – and with the Adafruit Voice Bonnet, you can give it a mouth and ears as well! Featuring two microphones and two 1 Watt speaker outputs using a high-quality I2S codec, this Pi add-on will work with any Raspberry Pi with a 2×20 connector – from the Pi Zero up to the Pi 4 and beyond (basically all but the very first ones made).
The on-board WM8960 codec uses I2S digital audio for great quality recording and playback – so it sounds a lot better than the headphone jack on the Pi (or the no-headphone jack on a Pi Zero). We put ferrite beads and filter capacitors on every input and output to get the best possible performance, and all at a great price.
We specifically designed this bonnet for use with making machine learning projects such as DIY voice assistants – for example, see this guide on creating a DIY Google Assistant. But you could do various voice-activated or voice recognition projects. With two microphones, basic voice position can be detected as well.
- WM8960 codec uses I2S digital audio for both input and output
- On/Off privacy switch to deactivate audio so you know it can’t be recording.
- Two analog microphone inputs (left and right)
- Two 1W speaker outputs
- 3.5mm stereo headphone or line-out audio
- Plugs into any Raspberry Pi with 2×20 headers
With the extra space on the PCB, we also added some bonus extras!
- Pushbutton – Use to change modes, activate the voice assistant, anything you like!
- Three DotStar RGB LEDs – add LED feedback or make a rainbow light show
- STEMMA QT connector – plug in any of our I2C sensors, OLEDs, or accessories.
- 3-Pin JST STEMMA connector – for larger accessories, like NeoPixels, a relay, or servo
No assembly required! Simply pop it onto your Pi and install the microphone/speaker card using our installer script. Your Pi will then have stereo input and output for use in any software – they appear as any other speaker/mic would. Play music or record audio with ease. For audio input, the two microphones are built into the Bonnet. For audio output, you can either use the Line-out/Headphone 3.5mm stereo jack or you can plug in one or two of our enclosed speakers. For DIY speakers, solder any 1W+ speaker to one of these JST 2-PH cables. If you’d like to stack another HAT or bonnet on top, use a 2×20 stacking header to feed through the 2×20 connector.
