The DJI O4 Air Unit Pro is the flagship of DJI’s next-generation O4 digital FPV transmission system, pushing the boundaries of range, latency, and image quality for both professional cinematic pilots and competitive racers. Weighing only 8.2 g (transmission module only) + 2×2.1 g antennas, this ultra-compact unit delivers an unprecedented maximum transmission distance of 15 km (FCC) when paired with DJI Goggles 3/N3, thanks to its true 2T2R dual-antenna design and intelligent frequency switching across 5.1/5.8 GHz bands.
Latency reaches a groundbreaking 15 ms in the new Racing Mode (1080p/100fps with Goggles 3), enabling up to 8 drones to race simultaneously without interference. For cinematic creators, the 1/1.3-inch CMOS sensor captures stunning 4K/120fps footage (16:9) or 4K/60fps (4:3) with a super-wide 155° FOV (12 mm equiv., f/2.8), D-Log M color profile, and RockSteady 3.0+ EIS (with full Gyroflow support). H.265 encoding pushes live feed quality up to 1080p/100fps at 130 Mbps, ensuring buttery-smooth, artifact-free visuals even at extreme speeds.
Additional pro-grade features include compatibility with Avata 2 ND filters (ND8/16/32) for perfect exposure in bright sunlight, Canvas Mode + full Betaflight OSD customization, built-in 4 GB storage + microSD slot (up to 512 GB), and wide voltage input (7.4–26.4 V). The system works seamlessly with DJI Goggles 3, N3, Goggles 2, Integra, and corresponding FPV Remote Controllers 2/3. With mounting holes at both 20×20 mm and 25.5×25.5 mm, it fits everything from tiny whoops to large 7–13-inch cinematic rigs.
Whether you’re chasing gates at 200 km/h or filming sweeping alpine landscapes, the DJI O4 Air Unit Pro redefines what’s possible in lightweight digital FPV.
