4.2. Pin Soldering (If required)
If your module did not come with pre-soldered pin headers, you will need to solder them to the board. This process involves carefully attaching the header pins to the designated pads on the development board using a soldering iron and solder wire. Ensure proper ventilation and safety precautions during soldering.

5. Operating Instructions
5.1. Firmware Flashing
To program the ESP32 module, you will need to flash firmware onto it. This typically involves connecting the module to your computer via the USB-C port and using a compatible Integrated Development Environment (IDE) such as MicroPython or Arduino IDE. The module supports automatic download, simplifying the flashing process.

6. Troubleshooting
- Module not recognized by computer: Ensure the USB-C cable is fully inserted and functional. Verify that the necessary USB drivers (e.g., CP210x drivers for the onboard USB-to-UART bridge) are installed on your computer.
- Firmware upload failure: Check your IDE settings for the correct COM port and board selection. Ensure the module is in programming mode (if manual mode is required, though this module supports automatic download).
- External components not working: Double-check all wiring connections against your circuit diagram. Verify power supply to external components and ensure correct pin assignments in your code.
- Wi-Fi/Bluetooth connectivity issues: Ensure your antenna is properly connected (if external) or that the onboard antenna is not obstructed. Verify network credentials and configurations in your code.
7. Maintenance
- Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid liquid cleaners.
- Storage: Store the module in an anti-static bag in a cool, dry place when not in use to prevent electrostatic discharge and moisture damage.
- Handling: Handle the module by its edges to avoid touching sensitive components and pins.
8. Warranty and Support
