Best Value Dev Board
For the price, you cannot beat the feature set. Having Wi-Fi, Bluetooth, a decent screen, and a camera on one board makes it ideal for rapid prototyping of IoT devices.

Excellent for University Projects
Used this for my final year project on smart home control. The voice recognition accuracy is impressive, and the community support for ESP32-S3 is huge. Highly recommended for students.

All-in-One Solution
I love that I don't need to wire up separate modules for the screen, camera, and mic. It saved me hours of prototyping time. The build quality from Waveshare is excellent as always.

Great Hardware, Steep Learning Curve
The hardware itself is top-notch. The ESP32-S3 handles the display and camera without lag. However, getting the deep learning models optimized required some patience. Documentation could be slightly more detailed for beginners.

Perfect for AI Voice Projects
This board is incredible for building voice assistants. The integration with the Xiaozhi AI framework was seamless, and the microphone quality is surprisingly good for a dev board. The touch screen is responsive and bright.

Solid Performance
Runs the demo firmware out of the box perfectly. The camera feed on the LCD is clear. Only minor issue is that the speaker output is a bit quiet, but easy to amplify externally.
Q: What is the power consumption when the screen is on?
A: With the screen brightness at 100% and Wi-Fi active, the board draws approximately 250-300mA. We recommend using a stable 5V/2A power source for optimal performance.
Q: Does this board come pre-flashed with the Xiaozhi AI firmware?
A: Yes, the board typically comes with a demo version of the Xiaozhi AI voice assistant pre-installed. You can also easily flash your own custom firmware using the Arduino IDE or ESP-IDF.
Q: Can I use this with Python/MicroPython?
A: Absolutely. The ESP32-S3 chip fully supports MicroPython and CircuitPython. You will need to flash the appropriate interpreter binary to get started.
Q: Is the camera replaceable if it gets damaged?
A: The camera module is connected via a standard FPC connector. While it is technically replaceable if you have soldering skills and a replacement OV2640 module with the same pinout, it is not designed for frequent swapping.
Q: Does it support external antennas for better Wi-Fi range?
A: The board features an onboard PCB antenna which works well for most applications. There is no dedicated U.FL connector for an external antenna on this specific model, but the onboard antenna provides reliable connectivity within standard ranges.
