4. Prepare Development Environment: Set up your chosen IDE (e.g., Arduino IDE) with the correct board definitions for ESP32-C3.
5. Микропрограмманы жүктөө: Follow the specific burning guide provided by LILYGO for detailed instructions on uploading your program. A general guide can be found at: zbhci.readthedocs.io/en/latest/user-guide/burning.html

Маанилүү эскертүү: Some users have reported issues when using USB-C to USB-C cables for power or data transfer. It is recommended to use a USB-A to USB-C cable for reliable operation and programming.

3. Operating the T-Zigbee Board

The LILYGO T-Zigbee board offers flexible operation due to its dual MCU architecture. You can configure the board to operate primarily with either the ESP32-C3 or the TLSR8258 chip, depending on your application's requirements.

3.1 Working Mode Switch

The board features a DIP switch for selecting the working mode. Refer to the pin map for the exact location and configuration of this switch.

Figure 3: LILYGO T-Zigbee Pin Map and DIP switch mode settings.

• TLSR8258 Work Mode: Toggle the DIP switch as shown in the pin map to enable the TLSR8258 for Zigbee, BLE Mesh, etc.
• ESP32-C3 Work Mode: Toggle the DIP switch as shown in the pin map to enable the ESP32-C3 for Wi-Fi and Bluetooth LE.

3.2 Pinout Information

Understanding the pinout is crucial for connecting peripherals and integrating the board into your projects. The board provides clear labels for both ESP32-C3 and TLSR8258 pins.
