Great hardware, steep learning curve
The build quality is excellent and the screen is vibrant. However, getting the DeepSeek models optimized required some tweaking of the memory settings. Overall a solid dev board.

Amazing display quality
The colors on this IPS panel are stunning. I'm using it for a retro gaming emulator project and the frame rates are surprisingly good thanks to the PSRAM.

Solid for industrial HMI prototypes
We are using this for initial HMI concepts in our factory automation projects. The touch response is accurate, though we wish it had more exposed GPIO pins for sensors.

Perfect for AI IoT Projects
The integration of the 3.5-inch touchscreen with the ESP32-S3 makes this board incredible for building standalone AI interfaces. The XiaoZhi interaction features work smoothly out of the box.

Best value for money
I've used many ESP32 boards, but the included high-res capacitive screen saves so much time and wiring. It's ready to go for prototyping smart home dashboards immediately.
Q: Is the touchscreen multi-touch capable?
A: The capacitive touchscreen on this model supports single-touch operations primarily designed for UI interaction. Multi-touch gestures may have limited support depending on the driver library used.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: You should connect the LiPo battery through a dedicated charging module or to the BAT pin if your specific revision supports direct battery input with built-in charging. Do not connect a raw battery to the 5V USB pin.
Q: Does this board come with pre-flashed firmware for the XiaoZhi AI?
A: Yes, the board typically ships with a demo firmware that showcases the XiaoZhi AI interaction capabilities. You can also easily flash your own custom firmware via the USB-C port.
Q: Which Python version is compatible with MicroPython on this board?
A: This board supports MicroPython v1.20 and later. We recommend checking the Waveshare wiki for the specific build configuration optimized for the ESP32-S3 and the onboard LCD.
Q: What is the maximum resolution supported for video playback?
A: While the screen native resolution is 480x320, smooth video playback depends on the codec and frame rate. For best performance, we recommend optimized low-resolution clips or animated UI elements rather than full HD video.
