The latest Air Unit O3 is not only smaller and lighter, but also provides a much longer range than its predecessor. With O3+ video transmission, the DJI O3 Air Unit provides multiple powerful video transmission capabilities and a range of up to 10 km. Control your drone with quick response and get a clear, ultra-sharp live feed. 2T2R omnidirectional antennas further ensure the stability and smoothness of video transmission within the signal coverage range.

The DJI O3 Air Unit features a wireless video transmission resolution of up to 1080p while maintaining a high frame rate of 100 fps. It also supports H.265 video encoding format, bringing extra clarity and smoothness to your live view. The built-in 20GB flash memory is also a great addition, allowing you to record the journey of your flights at 4K@60fps or 2.7K@120fps for slow motion photos.

Key specifications:

  • Embedded remote controller receiver (compatible with DJI FPV transmitter 2);
  • O3+ low-latency 30 ms 10 km Digital Video Transmission;
  • Multi-antenna anti-interference digital transmission;
  • 1080p/100fps H.265 Video Transmission;
  • Onboard 4K@60fps video recording;
  • RockSteady electronic image stabilization (EIS);
  • Wide range of voltage input (7.4-26.4 V / 2-6S compatible);
  • Canvas mode with full Betaflight OSD Support and PID adjustment;
  • Compatible with Multiple DJI Devices (Goggles 2, FPV Goggles V2, and FPV controller 2).

At first glance:

The O3 Air Unit consists of a camera, video transmitter, and antenna with a total weight of approximately 40 grams (1.41 ounces). The O3 VTX device measures 32.5 × 30.5 × 14.5 mm and has an FC connector, a camera socket, a USB Type-C connector, a micro SD slot, a status LED and a connect button. It has a 25.5 × 25.5 mm mounting pattern with M1.6 screws. The case is made of sturdy aluminum that doubles as a heatsink, so expect it to get very hot during use. In fact, without good airflow, it's not recommended to keep it on for more than a few minutes.

The new Air Unit has two separate U.FL antenna connectors. To save some space and allow easy installation, DJI put two antennas in one housing so that it looks like one antenna. It operates at 2.4 GHz for RX and 5.8 GHz for RX/TX frequencies. While in FCC (USA) mode the maximum possible range is 10 km (6.21 mi), in CE (Europe region) mode it is only 2 km (1.21 mi).

The camera module measures 21.2×20×19.5 mm, with two mounting screws on each side. According to DJI, their O3 AU Camera Module is compatible with the DJI Avata ND Filters Set (ND8/16/32). Its 1/1.7-inch sensor and f/2.8 lens deliver shots with a super-wide field of view (FOV) of 155° for stunning visual effects. DJI uses the same sensor in many recent products, such as the Avata drone, the Action 3 and the Pocket 2 gimbal camera. D-Cinelike color mode allows more creative freedom for color grading, allowing you to process and adjust footage. Additionally, the O3 Air Unit features RockSteady, DJI's game-changing Electronic Image Stabilization (EIS) technology. In addition, IMU data is stored so that footage can be further stabilized in compatible software using gyroscope-based information.
