Excellent Display Quality
I bought this primarily for the screen and it did not disappoint. Colors are vibrant and viewing angles are excellent. The battery life is decent for a development board with this resolution.

Impressed by the Documentation
Waveshare's wiki and example codes made getting started very easy. I had a basic clock running with weather data within an hour. The magnetic charging is also a nice touch.

Good Value but Needs Better Strap Options
The board itself is fantastic for the price. My only complaint is that finding compatible watch straps for this specific form factor takes some searching. Otherwise, highly recommended for learners.

Solid Choice for AI Projects
The integration with XiaoZhi AI opens up many possibilities for voice-controlled projects. The microphone sensitivity is good, and the processing power is sufficient for local inference tasks.

Great Hardware, Steep Learning Curve
Hardware quality is top-notch as expected from Waveshare. The ESP32-S3 handles graphics well. However, beginners might find the initial environment setup a bit challenging without prior ESP-IDF experience.
Q: Does this board support MicroPython or only C++?
A: Yes, the ESP32-S3 chip fully supports MicroPython, CircuitPython, and the standard ESP-IDF (C/C++). You can choose the environment that best fits your project needs.
Q: What is the maximum current draw for GPIO pins?
A: Each GPIO pin can source or sink up to 40mA. However, the total current drawn from all pins combined should not exceed the chip's maximum rating to prevent damage. Please refer to the ESP32-S3 datasheet for detailed limits.
Q: Can I replace the battery if it degrades over time?
A: The battery is connected via a small JST connector, making it replaceable. Please ensure you use a Li-polymer battery with similar dimensions and voltage specifications (3.7V).
Q: Is the touchscreen resistant to scratches?
A: The screen comes with a standard protective layer suitable for development and prototyping. For final products intended for daily wear, we recommend applying an additional tempered glass protector.
Q: Does the XiaoZhi AI require an internet connection to function?
A: XiaoZhi AI can perform basic local commands offline. However, for advanced natural language processing and cloud-based services, an active Wi-Fi connection is required.
