Good board, runs a bit warm
Functionality is great for the price. The Wi-Fi connection is stable, and the camera interface works well for our security prototype. Just note that it gets slightly warm during prolonged video processing, so consider ventilation.

Best Korvo-2 variant available
I've tried other development boards, but this one offers the best balance of peripherals and performance for the XiaoZhi ecosystem. The support for RGB screens makes UI development much more engaging.

Excellent value for multimedia dev
We bought five of these for our university lab. Students love the built-in screen and audio capabilities. It simplifies the setup for complex multimedia projects significantly. The video intercom demo ran out of the box.

Smooth performance with ESP-IDF
Compiling and flashing using ESP-IDF was straightforward. The board supports high-resolution graphics well, and the touch response on the connected screen is very responsive. A solid choice for professional prototyping.

Perfect for AI Voice Projects
This board is exactly what I needed for my XiaoZhi Lexin project. The RGB screen integration was seamless, and the dual microphones pick up voice commands clearly even from a distance. Highly recommended for IoT developers.

Great hardware, documentation could be better
The hardware quality is top-notch. The ESP32-S3 handles video intercom tasks without lag. However, finding specific pinout details for the RGB interface took some digging in the forums. Once set up, it works flawlessly.
Q: What is the maximum resolution supported for the display?
A: The board supports RGB screens with resolutions up to 800x480 pixels, depending on the specific screen module used and the memory allocation in your firmware.
Q: Does it support over-the-air (OTA) updates?
A: Yes, since it is based on the ESP32-S3 chip, it fully supports OTA updates via Wi-Fi, allowing you to remotely update your firmware easily.
Q: Does this board come with the RGB screen included?
A: No, the development board is sold separately. It features the necessary interface connectors to support standard RGB LCD screens, which must be purchased independently.
Q: Is this compatible with the standard Arduino IDE?
A: Yes, this board is fully compatible with the Arduino IDE when you install the ESP32 board manager package. You may need to select the specific ESP32-S3 variant in the tools menu.
Q: Can I use this for a standalone video doorbell project?
A: Absolutely. The board includes a camera interface (DVP), Wi-Fi connectivity, and audio processing capabilities, making it ideal for building standalone video intercom or doorbell systems.
