DJI gives tiny FPV drones a much bigger view

Sometimes, a wider view can make a bigger difference than a better camera. That’s the thinking behind DJI’s latest addition to its FPV lineup. The company has introduced the DJI O4 Wide Air Unit, an ultra-wide version of the O4 Air Unit that swaps the standard camera lens for a much broader 159-degree field of view. Everything else that made the original appealing, including its lightweight design, 4K recording, and low-latency digital video transmission, largely stays the same.

The result is a camera and transmission module built specifically for pilots who want a more immersive flying experience without adding extra weight to their custom FPV drones.

If you’re unfamiliar with DJI’s Air Unit lineup, these aren’t complete drones. Instead, they’re compact camera and digital video transmission systems designed for DIY FPV aircraft. Builders install them on custom drones to stream a live HD video feed to compatible DJI FPV goggles while also recording flight footage onboard to a microSD card.

The O4 Air Unit family first debuted in January 2025, bringing DJI’s latest O4 digital transmission technology to lightweight FPV builds. The standard O4 Air Unit weighs just 8.2 grams, making it suitable for smaller drones where every gram counts. The new O4 Wide Air Unit tips the scales at 13 grams, including the camera, and is aimed squarely at 2-inch and smaller micro FPV drones.

Its headline feature is the jump from the standard model’s 117.6-degree field of view to an expansive 159 degrees.

That wider perspective allows pilots to capture much more of the surrounding environment in every frame. Whether you’re weaving through trees, flying tight indoor spaces, or shooting cinematic proximity lines, the extra field of view can make footage feel faster, more immersive, and more dynamic.

Beyond the new lens, the core specifications remain familiar. The O4 Wide Air Unit uses the same 1/2-inch image sensor as the standard model and records 4K video at up to 60 frames per second. DJI’s O4 transmission system supports 1080p live video at up to 100fps using H.265 encoding, while FCC transmission range reaches up to 10 kilometers under ideal conditions.

DJI is also continuing to improve the experience for racing pilots. The O4 Air Unit series introduces a dedicated Racing Mode, with latency dropping as low as 15 milliseconds under supported configurations. The O4 Wide Air Unit itself is rated for latency as low as 20 milliseconds, helping pilots maintain a responsive video feed during high-speed flights. DJI also says the system supports up to eight aircraft racing simultaneously, making it suitable for organized FPV race events.

The new model joins a growing O4 Air Unit family rather than replacing any existing product.

The original O4 Air Unit remains the lightest option for pilots who want to keep overall aircraft weight to an absolute minimum. Meanwhile, the O4 Air Unit Pro targets builders looking for the highest image quality, pairing a larger 1/1.3-inch image sensor with 4K recording at up to 120fps and a dual-antenna design capable of transmission distances of up to 15 kilometers under FCC standards.

The new Wide version sits neatly between those two products. It retains the compact form factor and core imaging performance of the standard O4 Air Unit but offers a significantly wider field of view for pilots who prioritize immersive footage over absolute minimum weight.

For existing DJI FPV users, it also provides another option without requiring a completely different ecosystem. The O4 Air Unit series is compatible with DJI’s latest FPV goggles and controllers, making it an easy upgrade path for builders already invested in DJI’s digital FPV platform.

For many FPV pilots, choosing between the three models will likely come down to a simple question: Do you want the lightest setup, the best image quality, or simply the widest possible view? With the new O4 Wide Air Unit, DJI now has a dedicated answer for that last group.
