Great hardware, documentation could be better
The board itself is powerful and the capacitive touch works flawlessly. However, finding specific examples for the DeepSeek integration required some digging in the forums.

Excellent value for money
Coming from older ESP32 boards, the S3 chip with PSRAM makes a huge difference when running graphical interfaces. The rounded LCD looks very modern.

Solid for industrial HMI prototypes
We are using these for preliminary HMI designs. The build quality is good, though we wish it had a wider operating temperature range specified for harsh environments.

Best learning board for students
I used this for my final year project. The ability to run MicroPython directly on the touchscreen made prototyping incredibly fast. Highly recommended for education.

Touch response is amazing
The capacitive touch is much smoother than resistive screens I've used before. The AI interaction features add a fun layer to standard IoT projects.

Perfect for AI IoT Projects
The integration with XiaoZhi AI is seamless. The screen is bright and responsive, making it ideal for building smart home dashboards. Setup took less than an hour.
Q: What is the maximum brightness level of the LCD?
A: The display offers adjustable brightness via software PWM, reaching up to approximately 450 nits, which ensures good visibility even in moderately lit indoor environments.
Q: Are there example codes available for the capacitive touch gestures?
A: Yes, our GitHub repository contains a comprehensive library with examples for swipe, tap, and multi-touch gestures specifically optimized for the GT911 driver on this board.
Q: Can I power this board with a Li-Po battery?
A: Absolutely. There is a dedicated JST connector for Li-Po batteries (3.7V). The board includes charging circuitry, so you can charge the battery via the USB-C port.
Q: Does this board support external camera modules?
A: Yes, the ESP32-S3 supports DVP camera interfaces. You can connect compatible OV2640 or OV5640 modules to the exposed GPIO pins for image processing projects.
Q: Is the XiaoZhi AI feature pre-installed or do I need to flash it?
A: The board comes with a demo firmware showcasing XiaoZhi AI, but for custom development, you will need to flash your own code using ESP-IDF or Arduino IDE to fully utilize the AI capabilities.
