Responsive and Fast
The response time for voice commands is incredibly fast. It feels very similar to the commercial Xiao Shisan product but gives me full control over the code.

Best value for money
I've tried several development boards, but this one offers the best balance of price and features for voice-controlled robots. The battery life is decent when optimized.

Perfect for DIY AI Projects
This board is exactly what I needed to build a custom voice assistant. The integration with the XiaoZhi AI platform was seamless, and the audio quality is surprisingly good for such a small form factor.

Good but needs soldering
The board itself is excellent, but it came without headers soldered on. As a beginner, I had to ask a friend to help me solder them before I could use it in a breadboard.

Great hardware, documentation could be better
The ESP32-C3 chip performs well and the OLED screen is crisp. However, setting up the initial firmware required some digging through community forums. Once running, it works like a charm.
Q: What is the maximum microphone range?
A: With the default onboard microphone, the effective recognition range is approximately 3 to 5 meters in a quiet environment. For better range, you can connect an external microphone module via the I2S pins.
Q: Does this board come with a pre-installed battery?
A: No, the board does not include a battery. It supports standard 3.7V Li-Po batteries which must be purchased separately and connected via the JST connector.
Q: Is the XiaoZhi AI service free to use?
A: The basic access to the XiaoZhi AI cloud platform is currently free for developers during the beta phase. Please check the official documentation for the latest pricing tiers for commercial deployment.
Q: Can I program this using Python?
A: Yes, this ESP32-C3 based board is fully compatible with MicroPython. You can also use C++ via Arduino IDE or the native ESP-IDF framework.
Q: Does it support Bluetooth audio streaming?
A: Yes, the ESP32-C3 chip supports Bluetooth 5 LE. While primarily designed for voice command data transmission, it can be configured for A2DP audio streaming with custom firmware.
