The FPV community is buzzing with excitement about the upcoming DJI O4 Air Units. Leaks suggest that DJI will release two versions: the DJI O4 Pro Air Unit and the DJI O4 Lite. These new air units promise exciting upgrades, enhanced performance, and competitive pricing. Below, we explore the most intriguing details about these innovative products.
What Are DJI O4 Air Units?
The DJI O4 Air Units are camera and video transmitter modules. They transmit HD video while recording high-quality footage comparable to high-end action cameras. By integrating these units, drone builders can reduce weight and cost, as there is no longer a need for a separate action camera. Additionally, they simplify the setup process.
The O4 Pro caters to professional users with advanced features, while the O4 Lite offers a lighter, budget-friendly alternative. Both versions are expected to support Betaflight OSD, provide improved image quality, and feature DJI’s RockSteady 3.0 stabilization technology.
Key Features of the DJI O4 Pro
The DJI O4 Pro targets FPV enthusiasts seeking superior image quality and performance. Its specifications highlight its capability:
- FPV Live Feed: Delivers 1080p at 60Mbps on Goggles 3 and N3 (1080p at 50Mbps on Goggles 2 and Integra).
- Onboard Recording: Supports up to 4K at 60FPS at 130Mbps, including D-Log M.
- Storage: Includes a microSD card slot.
- OSD Support: Compatible with Betaflight and iNav.
- Image Sensor: Features a 1/1.3″ sensor with an F2.0 aperture.
- Stabilization: Integrates RockSteady 3.0.
- Antenna: Includes dual antennas.
- RF Output: Produces 33dBm.
- Size and Weight: Camera width is 20mm, with an air unit size of 33.5 x 33.5 x 13mm and a weight of 31g.
- Mounting Options: Supports 20x20mm and 25.5×25.5mm configurations.
- Price: Rumored to cost around $210.
The larger 1/1.3″ sensor and F2.0 aperture significantly improve low-light performance, providing better results than the DJI Avata 2’s F2.8 aperture.
DJI O4 Lite: Features and Benefits
The DJI O4 Lite appeals to those who prefer a lighter and more affordable option without compromising image quality. Here are its main specifications:
- Input Voltage: Operates on 1S to 3S.
- FPV Live Feed: Delivers 1080p at 60Mbps on Goggles 3 and N3 (1080p at 50Mbps on Goggles 2 and Integra).
- Onboard Recording: Supports 4K at 30FPS.
- Storage: Includes built-in 26GB memory (no SD card slot).
- OSD Support: Compatible with Betaflight and iNav.
- Image Sensor: Features a 1/2″ sensor.
- Stabilization: Integrates RockSteady 3.0.
- RF Output: Produces 30dBm.
- Size and Weight: Camera width is 14mm, with an air unit size of 30 x 30 x 6mm and a weight of 10g.
- Mounting Options: Supports 20x20mm and 25.5×25.5mm configurations.
- Price: Rumored to cost around $120.
The O4 Lite is perfect for lightweight FPV builds, such as cinewhoops, toothpicks, and tiny whoops. It matches the DJI Neo’s image quality, making it an excellent choice for ultra-light setups.
Racing Mode for Ultra-Low Latency
One of the standout features of both the O4 Pro and O4 Lite is Racing Mode. This mode drastically reduces latency, which is critical for FPV racing. The O4 Pro achieves latency as low as 15ms, while the O4 Lite manages around 20ms with Goggles 3 and N3. These features could revolutionize FPV racing by offering faster response times and minimizing desync during high-speed maneuvers.
However, Racing Mode is only compatible with Goggles 3 and N3. Using Goggles 2 or Integra may lead to slightly higher latency.
Final Thoughts
The leaked specifications of the DJI O4 Pro and O4 Lite Air Units hint at an exciting future for FPV flying. These units combine advanced image quality, ultra-low latency, versatile mounting options, and lightweight builds. If these rumors are accurate, DJI’s O4 Air Units will likely set a new standard in the digital FPV market.
We eagerly await DJI’s official announcements regarding availability and pricing. Stay tuned for more updates as they come.
