Exceeded expectations
The screen resolution is sharper than I expected for this price point. Running complex LVGL animations is smooth thanks to the PSRAM. It's now my go-to board for any project requiring a visual interface.

Best value ESP32-S3 box
I've tried several similar boards, but the XiaoZhi 2.2 offers the best balance of price and performance. The Wi-Fi connection is stable, and the touch response is very sensitive. Great for prototyping smart home controls.

Solid for industrial prototyping
We used this for a quick proof-of-concept for a control panel. The build quality feels robust enough for initial testing. The only downside is the battery management features are basic, so we added an external BMS.

Fantastic learning tool
As someone new to embedded systems, this board was perfect. The pre-loaded demos helped me understand how the microphone and camera work together. The community support is also very active and helpful.

Great hardware, documentation could be better
The hardware quality is top-notch, especially the screen clarity and camera module. However, finding specific examples for the MCP camera interface took some digging in the forums. Once figured out, it works flawlessly.

Perfect for AI Voice Projects
This board is incredibly easy to set up for voice assistant projects. The dual microphones provide excellent noise cancellation, and the LVGL integration makes building a custom UI a breeze. Highly recommended for IoT enthusiasts.
Q: Can I power this device with a LiPo battery?
A: The board has a JST connector for a LiPo battery, but please note it lacks a dedicated charging circuit. You should use a charged battery or an external charger module.
Q: Does this board support MicroPython out of the box?
A: Yes, the XiaoZhi AI 2.2 is fully compatible with MicroPython and CircuitPython. You can flash the firmware via the USB-C port using standard tools.
Q: Are there example codes available for the dual microphone array?
A: Yes, our GitHub repository contains several examples demonstrating beamforming and noise cancellation using the dual I2S microphones with the ESP-IDF framework.
Q: What is the resolution of the included camera?
A: The board comes with an OV2640 camera module which supports resolutions up to UXGA (1600x1200), though it is commonly used at lower resolutions like VGA or QVGA for faster processing.
Q: Is the touchscreen resistive or capacitive?
A: The 2.4-inch display features a capacitive touch panel, offering multi-touch support and a more responsive user experience compared to resistive screens.
