Description

The CaddxFPV Polar Air Unit integrates a high-sensitivity starlight camera with a digital video transmitter, engineered for FPV racing and freestyle drones. Its 1/1.8-inch sensor and F/1.6 lens provide exceptional clarity in low-light conditions, while the 5.8GHz digital link ensures stable, low-latency HD video up to 4km under FCC regulations.

Designed for seamless integration, the unit features a 3-in-1 port for simplified wiring to compatible flight controllers, a USB-C port for firmware updates, and a microSD slot for onboard DVR. Its robust aluminum housing provides effective heat dissipation for sustained high-performance operation.

Key Features

  • Advanced Starlight Sensor: 1/1.8-inch CMOS sensor with 0.00003 Lux sensitivity for night and dusk flying.
  • High-Frame-Rate Digital Link: Transmits 720p video at 120fps with a minimum 28ms system latency.
  • Extended Operational Range: Achieves up to 4km transmission distance in FCC/SRRC regions (0.7km CE).
  • Multi-Drone Support: Capable of supporting up to 8 drones simultaneously on 8 distinct channels.
  • Integrated Thermal Design: Aluminum alloy housing acts as a heatsink for reliable continuous operation.
  • Simplified Connectivity: 3-in-1 cable port reduces wiring complexity for power, video, and control signals.
  • Broad Voltage Input: Accepts 7.4V to 17.6V (2S to 4S LiPo), compatible with most FPV power systems.

Applications

  • 5-inch FPV Racing Drones requiring low-latency, high-quality digital video feed.
  • Freestyle and Cinematic FPV Drones benefiting from the starlight sensor for dusk/night flights.
  • Compact Long-Range Builds where the 4km digital link and small form factor are advantageous.
  • Betaflight-based drones seeking plug-and-play integration with the 3-in-1 cable system.
  • Builds compatible with DJI FPV Goggles V2 or Goggles 2 for a complete digital HD FPV experience.

Frequently Asked Questions

What is the input voltage range for the CaddxFPV Polar Air Unit?

The CaddxFPV Polar Air Unit accepts a wide input voltage range of 7.4V to 17.6V. This makes it directly compatible with standard 2S, 3S, and 4S LiPo battery packs commonly used in FPV drones without requiring an external voltage regulator.

Is the CaddxFPV Polar compatible with DJI FPV Goggles?

Yes, the CaddxFPV Polar Air Unit operates on the DJI digital FPV protocol and is fully compatible with DJI FPV Goggles V2 and Goggles 2. It provides a seamless digital video link, supporting up to 8 channels for multi-pilot flying.

What is the benefit of the 'starlight' sensor?

The 1/1.8-inch starlight sensor offers extremely high sensitivity, with a minimum illumination of 0.00003 Lux. This allows the camera to capture usable video in very low-light conditions, such as at dusk, dawn, or under minimal ambient lighting, significantly extending usable flight times.

How do I update the firmware on the Polar Air Unit?

Firmware updates are performed via the USB-C port on the air unit. You will need to connect it to a computer and use the appropriate DJI or CaddxFPV update assistant software to download and install the latest firmware for optimal performance and feature support.

What mounting hardware is included?

The package includes six M2 screws in three different lengths (3mm, 4mm, and 5mm) and four gasket rings. This selection allows for flexible mounting to various frame thicknesses and provides vibration damping for cleaner video footage.

Package Includes

  • 1x CaddxFPV Polar Air Unit (with integrated camera)
  • 1x 3-in-1 Cable
  • 6x M2 Screws (3mm, 4mm, and 5mm lengths)
  • 4x Gasket Rings
