This manual provides essential information for the proper setup, operation, and maintenance of your thermal camera system, ensuring optimal performance and longevity.
Please read this manual thoroughly before using the product.
2. Setup
Careful installation and wiring are crucial for the correct functioning of your CADDXFPV Eclipse Thermal Camera. Follow the diagrams and instructions below for proper connection.
2.1 Component Overview
2.2 Wiring Connections
Ensure all connections are secure and correctly oriented to prevent damage to the device or associated components.
- Vin: Connect to power supply (11.1V ~ 25.2V).
- GND: Ground connection.
- Uart RX: UART Receive.
- Uart TX: UART Transmit.
- TX2, RX2, 5V0: Additional connections as indicated.
Connect the camera module to the main unit using the provided cable, ensuring the connectors are fully seated.
- CVBS: Composite Video Blanking and Sync output.
- GND: Ground connection.
- Power 9V~24V: Secondary power input.
- OSD: On-Screen Display connection.
- DP, DN, VBUS: Digital interface connections.
- GPIO0, GPIO1, GPIO2, RX, TX: General Purpose Input/Output and additional UART pins.
2.3 Power Supply Considerations
The VTX (Video Transmitter) component of the system generates significant heat during operation. Ensure your power supply can provide 12V@1.5A and that there is adequate airflow for heat dissipation to prevent overheating.
3. Operating Instructions
3.1 Operation Mode Switching
When utilizing the HD Thermal Imaging Camera, it is necessary to switch the device's operation mode. Specifically, you will need to change the 'Ground Side Device Mode' to 'Race Mode'.
To switch modes:
- Access the On-Screen Display (OSD) menu.
- Navigate to the 'Settings' section.
- Select 'Device'.
- Locate the 'Switch mode' option.
- Change the mode to 'Race'.
3.2 Viewing Thermal Imagery
Once properly configured, the thermal camera will output imagery to your connected display (e.g., FPV goggles or monitor). The display will show thermal data, often with an OSD overlay providing flight information.
4. Maintenance
To ensure the longevity and optimal performance of your CADDXFPV Eclipse Thermal Camera, follow these maintenance guidelines:
- Cleaning: Gently clean the camera lens with a soft, lint-free cloth. Avoid abrasive materials or harsh chemicals that could scratch the lens coating.
- Storage: Store the camera in a dry, cool environment, away from direct sunlight and extreme temperatures. Use protective caps for the lens when not in use.
- Handling: Handle the camera and its components with care. Avoid dropping or subjecting it to strong impacts, which can damage internal electronics or the thermal sensor.
- Firmware: Check the manufacturer's website periodically for firmware updates. Keeping the firmware updated can improve performance and add new features.
5. Troubleshooting
If you encounter issues with your CADDXFPV Eclipse Thermal Camera, refer to the following troubleshooting tips:
5.1 No Image on Display
- Check Power: Ensure the camera system is receiving adequate power (11.1V ~ 25.2V). Verify all power connections are secure.
- Video Output: Confirm the video output cable (CVBS or HD Interface) is correctly connected to your display device.
- Mode Setting: Verify that the operation mode is correctly set to 'Race Mode' as described in Section 3.1.
- Display Device: Test your display device (goggles/monitor) with another known working video source to rule out display issues.
5.2 Poor Image Quality
- Lens Cleanliness: Ensure the camera lens is clean and free from dust, smudges, or debris.
- Environmental Factors: Thermal camera performance can be affected by environmental conditions such as fog, heavy rain, or extreme temperature gradients.
- Power Fluctuations: Unstable power supply can lead to image degradation. Ensure a stable power source.
5.3 Overheating
- Airflow: Ensure the VTX and camera modules have sufficient airflow for cooling. Avoid enclosing them in tight spaces without ventilation.
- Power Draw: Verify that your power supply is capable of handling the camera's power requirements (12V@1.5A).

7. User Tips
While no specific user reviews or Q&A were provided, here are some general tips for FPV thermal camera users:
- Pre-Flight Check: Always perform a thorough pre-flight check of all connections and settings before each flight.
- Environmental Awareness: Thermal cameras excel in low-light or smoky conditions but can be affected by direct sunlight or reflective surfaces. Understand the limitations of thermal imaging in different environments.
- Mounting: Ensure the camera is securely mounted to your drone to minimize vibrations, which can degrade image quality.
- Heat Management: Given the VTX generates heat, ensure your drone's frame design allows for adequate ventilation around the camera system, especially during prolonged use.
