Robust build quality
The PCB feels sturdy and the components are well-soldered. I've been running it continuously for a week testing object detection algorithms without any overheating issues.

Great hardware, documentation could be better
The board itself is fantastic with plenty of RAM for image processing. However, finding specific pinout diagrams for the camera module required some digging in the GitHub repo. Still highly recommended.

Best value ESP32-S3 board
Compared to other boards with similar specs, this offers the best value. The built-in microphone works well for voice commands, and the Wi-Fi range is solid throughout my workshop.
Q: What camera modules are compatible with the DVP interface?
A: It supports standard DVP cameras like the OV2640 and OV5640. Please ensure the voltage level matches (3.3V) to avoid damaging the sensor.
Q: Can I power this board directly with a 3.7V Li-Po battery?
A: Yes, there is a dedicated JST connector for Li-Po batteries. The board includes a charging circuit, so you can charge the battery via the USB-C port while connected.
Q: Is the touchscreen resistive or capacitive?
A: This specific model features a resistive touchscreen. While it requires slightly more pressure than capacitive screens, it works reliably with styluses and in various environmental conditions.
Q: Does this board support MicroPython out of the box?
A: Yes, the ESP32-S3 chip is fully compatible with MicroPython. You will need to flash the latest firmware version that supports the specific LCD driver used on this board.
Q: How do I access the XiaoZhi AI features?
A: You can access XiaoZhi features by downloading the pre-configured SDK from our official GitHub repository. It includes libraries for voice recognition and natural language processing tailored for this hardware.
