Great hardware, steep learning curve
The ESP32-S3 chip is powerful and handles vision tasks well. However, setting up the environment for the large visual models required some patience. Worth it once running.

Excellent for Education
We bought ten of these for our university lab. Students love the voice chat features, and the board is robust enough to handle daily use in a classroom setting.

Solid performance
Used this to build a smart home assistant prototype. The Wi-Fi connection is stable, and the voice recognition latency is very low. Minor issue with the pinout diagram clarity.

Best value for money
Compared to other dev boards with similar specs, this offers unbeatable value. The camera and mic quality are surprisingly good for the price point.
Q: Do you provide sample code for the XiaoZhi voice chat feature?
A: Yes, we provide a GitHub repository with MicroPython and C++ examples specifically for implementing the XiaoZhi AI voice chat and visual interactions.
Q: Is it compatible with the standard Arduino IDE?
A: Yes, the ESP32-S3 is fully compatible with the Arduino IDE. You will need to install the ESP32 board manager package to get started.
Q: Can I power this directly from a 3.7V Li-Po battery?
A: Yes, there is a dedicated JST connector for Li-Po batteries. The board includes charging circuitry, so you can charge the battery via USB-C while connected.
Q: What is the maximum resolution supported for the camera input?
A: The board supports cameras up to 5MP, though performance with large visual models is optimal at VGA or lower resolutions depending on your code optimization.
Q: Does this board come with a camera module included?
A: No, the board includes the camera interface connector, but the camera module must be purchased separately to suit your specific resolution needs.
