Solid choice for student projects

We bought five of these for our university robotics club. They are durable and easy to program. The only minor issue is that the included screws were a bit short for thicker cases, but standard spacers worked fine.

Excellent sensitivity and clarity

The XMOS chip handles echo cancellation beautifully. I am using this for a custom smart speaker project, and the audio input quality rivals much more expensive commercial solutions.

Best value for voice AI development

I have tested several mic arrays, and this offers the best balance of price and performance. The beamforming works well, and the RGB LEDs provide great visual feedback for state changes.

Great hardware, documentation could be better

The microphone quality is excellent and the acoustic enclosure looks professional. I deducted one star because some of the Python library examples were outdated, but the community forums helped me resolve it quickly.

Perfect for Home Assistant Projects

This board integrated seamlessly with my Raspberry Pi 4. The far-field recognition is impressive; it picks up my voice clearly even when music is playing in the background. Setup took less than 20 minutes following the wiki.

Plug and play as advertised

Literally plugged it into the GPIO header, ran the install script, and it was working immediately. The noise cancellation is a game changer for my office environment.

5 FAQ

Q: Does the package include the microSD card?

A: No, the package includes the ReSpeaker HAT, acoustic enclosure, and mounting hardware. A microSD card with an OS installed must be purchased separately.

Q: Does this board work with Raspberry Pi 3 Model B+?

A: While primarily designed for the Pi 4B, it is compatible with the Pi 3B+ provided you have the correct pin alignment and power supply. However, performance may vary slightly due to CPU differences.

Q: Is an external power supply required?

A: No, the board can be powered directly through the Raspberry Pi's GPIO pins or USB port. However, if you connect high-power peripherals, we recommend a robust 3A power adapter for the Pi.

Q: What is the maximum distance for reliable voice detection?

A: In a quiet environment, the array can detect wake words up to 5 meters away. In noisy environments with background music or conversation, the effective range is typically around 3 meters.

Q: Can I use this with Alexa or Google Assistant directly?

A: Yes, the ReSpeaker board supports both Amazon Alexa and Google Assistant SDKs. You will need to configure the specific software image or install the respective SDKs on your Raspbian OS.
