Easy to get started
As a beginner, I found the Arduino library examples very helpful. I had a basic voice chat bot running within an hour of unboxing. Highly recommended for students.

Best value for ESP32-S3 learning
If you are looking to learn about edge AI or voice interfaces, this is the best starting point. The community support is growing, and there are already several open-source firmware projects available.

Compact and Powerful
I was surprised by how much power is packed into such a small form factor. The Wi-Fi connection is stable, and the voice recognition latency is impressively low when connected to the cloud API.

Perfect for AI Voice Projects
This board is incredible for building voice assistants. The ESP32-S3 handles the audio processing smoothly, and the OLED screen adds a nice visual touch for status updates. Setup with MicroPython was straightforward.

Solid board for prototypes
Used this to build a custom desk assistant. The OLED display is crisp, and the microphone sensitivity is good. Only minor issue is that the speaker output requires an external amplifier for louder volumes.

Great hardware, documentation could be better
The hardware quality is top-notch, and the N16R8 configuration provides plenty of memory for complex models. However, finding specific pinout diagrams for the audio codec took some digging in the GitHub repo.
Q: Does this board come with a built-in battery?
A: No, the XiaoZhi board does not include a built-in battery. It is powered via USB Type-C, but it features pads for connecting an external LiPo battery if needed for portable projects.
Q: Is the OLED screen touch-sensitive?
A: No, the 0.96-inch OLED screen included on this board is for display output only and does not support touch input.
Q: Can I run local LLMs on this device?
A: While the ESP32-S3 with 8MB PSRAM can run very small, quantized language models or specific keyword spotting algorithms locally, it is primarily designed to handle audio preprocessing and communicate with larger cloud-based AI models for full conversation capabilities.
Q: Is there a reset button on the board?
A: Yes, the board includes a dedicated RESET button to easily reboot the microcontroller during development and testing.
Q: What voltage logic level does the GPIO use?
A: The GPIO pins on the ESP32-S3 operate at 3.3V logic levels. Please ensure any connected sensors or modules are compatible with 3.3V to avoid damage.
