Frequently Asked Questions

How do I start using the pre-installed AI Xiaozhi firmware for voice chat?

Power the board via USB Type-C and connect to its Wi-Fi access point. Open a browser to the configured IP address to access the web interface. Follow the on-screen tutorial to configure Wi-Fi credentials and begin voice interaction. The system supports custom wake words and command sets via the provided configuration menus. You can test basic chat functions immediately after setup.

What development frameworks are compatible with this ESP32-S3 board?

The board is fully compatible with Espressif's ESP-IDF framework for low-level control and Arduino Core for ESP32 for simplified programming. You can also use MicroPython or PlatformIO. To switch from the pre-loaded AI firmware, you may need to erase flash using esptool.py. Connect the USB Type-C port to your computer and use the standard ESP32-S3 serial bootloader for flashing new applications.

Can I attach an external antenna to improve Wi-Fi range?

Yes, the board includes an IPEX (U.FL) antenna connector. You can attach a compatible 2.4GHz Wi-Fi antenna with an IPEX pigtail cable. Ensure the antenna is impedance-matched to 50 ohms. For optimal performance, detach or disable the onboard PCB antenna if present by configuring the relevant GPIO pin in your firmware. This is recommended for applications requiring extended range or placed inside enclosures.
