4. Setup and Installation

Follow these steps to set up your EWRF Micro Camera:

  1. Power Connection: Connect the camera to a DC 3V-5.2V power source using the PH1.25 2Pin connector. Ensure correct polarity (red wire for positive, black wire for negative).

5. Operation

The EWRF Micro Camera features a single button for controlling channels and power output, along with OSD for real-time information.

5.1 Channel and Power Switching

Locate the Channels/Power Switching Button on the camera module (refer to Figure 7). This button is used to cycle through available channels and adjust the transmitting power (25mW, 100mW, 200mW).

The camera supports 48 channels across 6 bands. Ensure your FPV receiver is set to the same channel and band as the camera for proper video reception. The channel frequencies are detailed in the table below:

Table displaying 48 FPV channels with their corresponding frequencies in MHz, organized by Band (A, B, C, D, E, F) and Channel (1-8).

5.2 On-Screen Display (OSD)

The integrated OSD module provides real-time telemetry data directly on your FPV feed. This includes:

  • Image transmission frequency (e.g., 5805)
  • Vehicle's battery voltage (e.g., 3.3V)
  • Transmitting power (e.g., 200mW)
  • Current channel/band information (e.g., A4)

5.3 Image Flip Function

The camera supports an image flip function, allowing you to adjust the video orientation as needed for different mounting configurations. Consult the product's specific button press sequence for activating this feature.

6. Maintenance

  • Keep the camera lens clean using a soft, lint-free cloth. Avoid abrasive materials.
  • Ensure all connections are secure before operation to prevent intermittent signal loss.
  • Store the camera in a dry, dust-free environment when not in use.
  • Avoid exposing the camera to extreme temperatures or direct sunlight for prolonged periods.

7. Troubleshooting

No video signal or black screen:
  • Check power connections to the camera and FPV receiver.
  • Ensure the camera and receiver are on the same frequency channel and band.
  • Verify the video system (PAL) is compatible with your receiver/goggles.
  • Inspect for any damaged wires or connectors.
Poor video quality (static, blurry, weak signal):
  • Check for obstructions between the camera and receiver.
  • Ensure antennas are properly connected and oriented.
  • Increase the transmitting power of the camera if possible (e.g., from 25mW to 100mW or 200mW).
  • Check for external interference from other 5.8G devices or strong electromagnetic fields.
  • Clean the camera lens if it appears blurry.
OSD data not displayed or incorrect:
  • Ensure the camera is receiving adequate power.
  • Verify the OSD feature is enabled (if applicable, though it's integrated).
  • Check for any firmware updates or configuration options if available (not detailed in current information).

8. Warranty and Support

For warranty information, technical support, or service inquiries, please refer to the seller's policies or contact the manufacturer directly. Keep your proof of purchase for any warranty claims.

9. Safety Warnings
