The DJI O4 Air Unit is a lightweight digital FPV camera and video transmission module for custom-built and small FPV drones. It pairs a camera with a 1/2-inch sensor (117.6° field of view, f/2.8) with an O4 transmission board. With the camera it weighs about 8.2 g. It records 4K at up to 60 fps to 23 GB of internal storage, uses RockSteady 3.0+ stabilisation and accepts 3.7 to 13.2 V input. With DJI Goggles 3 or Goggles N3 it transmits up to 10 km (FCC) with latency as low as 20 ms and bitrates up to 100 Mbps. A higher-specification O4 Air Unit Pro is sold separately.
