What’s DJI O4 Air Unit?
The DJI O4 Air Units are camera and video transmitter modules that are capable of transmitting HD video while recording high-quality footage that rivals high end action cameras. They reduce the weight and cost of your drone without using a action camera and simplify your setup. The O4 Pro focuses on higher-end features, while the O4 Lite offers a lighter, budget-friendly alternative. Both units are expected to support Betaflight OSD, improved image quality, and DJI’s RockSteady 3.0 stabilization technology.

The O4 Pro’s camera quality is expected to receive a major upgrade over the DJI O3, featuring a 1/1.3″ sensor and an F2.0 aperture for improved low-light performance. The O4 Pro is expected to share similar image quality to the Avata 2 drone, however, the larger aperture should offer even better low-light capability than the Avata 2, which has an F2.8 aperture.
Here’s a sample footage of the Avata 2:
In terms of FPV live feed, the O4 Pro is capable of transmitting 1080p video at 60Mbps to the Goggles 3 and N3 (1080p 50Mbps on Goggles 2 and Integra), similar to the Avata 2 on that regard.
DJI O4 Lite
Specifications
- Input Voltage: 1S to 3S
- FPV Live Feed: 1080p 60Mbps on Goggles 3 and N3 (1080p 50Mbps on Goggles 2 and Integra)
- Onboard Recording: 4K 30FPS
- Storage: Built-in 26GB Memory (No SD Card Slot)
- OSD Support: Betaflight & iNav
- Image Sensor: 1/2″
- Built-in Stabilization: RockSteady 3.0
- RF Output: 30dBm
- Camera Size: 14mm wide
- Air Unit Size: 30 x 30 x 6mm
- Mounting Options: 20×20mm and 25.5×25.5mm
- Weight: 10g
- Rumored Price: Around $120
The O4 Lite targets the micro FPV market, weighing under 10 grams and featuring a single-board design, which could make it a game-changer for micro quad builds such as cinewhoops, toothpicks or even tiny whoops. The O4 Lite is expected to be on par with the DJI Neo in image quality, making it an attractive option for lightweight setups.
Racing Mode for Ultra-Low Latency
A new Racing Mode promises to reduce latency to as low as 15ms on the O4 Pro and 20ms on the O4 Lite when used with Goggles 3 and N3. This could be a game-changer for FPV racers, offering faster response times that improve control and reduce the chance of desync during high-speed maneuvers. However, Racing Mode is only compatible with Goggles 3 and N3; if you’re using Goggles 2 or Integra, you may experience slightly higher latency.
Final Thoughts
While we’re still awaiting the official release, the leaked features and specifications of the DJI O4 Pro and O4 Lite Air Units paint an exciting picture for the future of FPV flying. From advanced image quality and low-latency Racing Mode to user-friendly mounting options and lighter builds, the O4 series is shaping up to be a versatile solution for a wide range of FPV enthusiasts.
Stay tuned as we continue to keep an eye on DJI’s official announcements. If the O4 Air Units and N3 Goggles are as capable as the rumors suggest, we’re looking at a significant evolution in DJI’s FPV offerings, and potentially a new standard in the digital FPV market.
