DJI Goggles and Air Unit Compatibility Guide: O4, O3 and Older Systems

Start with the full name of your goggles and the video unit on your aircraft. DJI Goggles 2 and DJI FPV Goggles V2 are different headsets, and a newer model number does not guarantee support for an older aircraft.

This guide helps you check a pairing, keep equipment that still fits your needs, and complete the video and control links separately. It covers Air Units used in custom-built and BNF FPV aircraft. DJI camera drones such as Neo and Avata have their own compatibility lists.

Part 3 of the RCDrone FPV Goggles series. Sources checked November 14, 2026. Manufacturer documentation and attributed owner reports inform this guide; these are not RCDrone bench-test results. For help choosing an ecosystem, start with the FPV goggles buying guide.

DJI goggles and Air Unit compatibility at a glance

Read the goggles row first. “Supported” still requires the appropriate firmware and operating mode. “Not listed” means the reviewed manufacturer support lists do not establish that pairing: do not buy it expecting compatibility. Legacy equipment has a separate firmware warning below.

Supported does not mean identical features

For O4, DJI reserves Racing mode for Goggles 3 and N3. Its specifications also distinguish available channel bandwidths by headset. Check the features you need before replacing goggles that already receive the picture. O4 specifications and test conditions.

Latency numbers describe a particular device combination and mode. They are not guaranteed response times for every flight. A camera's recording frame rate, the transmission mode and the headset's display refresh are separate specifications.

Firmware milestones worth checking

Swipe horizontally to view all columns.

Version formatting follows DJI's respective release notes. The O4 launch bundle predates O4 Wide; it is not a verified minimum-version list for Wide. Use the current device-specific updater and release instructions for that model.

Caddx Vista and RunCam Link belong in a separate legacy hardware check. Confirm the exact transmitter, camera and vendor firmware instructions; the original Air Unit column is not blanket approval for every legacy kit. Buying a used unit without its firmware details can turn a simple headset purchase into a migration job.

Identify the equipment you actually own

Photograph the headset label and record the model shown in its settings. On the aircraft, identify the installed video transmitter, not just the frame name. Compare it with the selected order variant: the same frame can be sold with different cameras, video systems and control receivers.

Keep four entries in your notes: goggles, Air Unit, radio receiver, firmware versions. A listing marked “O4 + ELRS 2.4GHz” describes two links. The O4 sends video to a compatible headset; ELRS handles control through its own receiver.

A fleet decision needs more than one tick in a table. List every aircraft you intend to fly over the next year. Mark the combinations that work now, the ones that need changes, and the ones you would stop using. The cheapest headset can become the expensive choice if it forces several aircraft conversions.

Goggles 3 or Goggles N3: compare fit after compatibility

Goggles 3 offers adjustable IPD and built-in diopter adjustment; N3 uses a single-screen design without IPD adjustment and is designed to accommodate personal glasses. These are different ways to fit a display to your eyes. Goggles 3 fit guidance · N3 fit guidance.

Try reading the OSD at all four corners while holding your normal flying posture. Check nose pressure, light leakage and whether your glasses shift when you move your head. A specification sheet cannot tell you whether the image stays comfortable for an entire battery pack.

If both cover your aircraft, compare DJI Goggles 3 and DJI Goggles N3 with the same shopping list beside them. Include any corrective lenses, storage and charging accessories. For a mixed O3/O4 fleet, the compatibility difference matters before the price difference.

O4, O4 Wide, O4 Pro or O3: check the installation

There are three O4 products in DJI's current FAQ. Wide adds a wider camera view to the lightweight O4 approach; Pro has a different camera and transmission-module package. Keep the exact name on the parts list rather than treating every “O4” item as interchangeable.

Swipe horizontally to view all columns.

Supply ranges: O4 series manual, installation wiring table and O3 specifications. Supply voltage and current capacity both matter. The standard O4 and Wide must not inherit a high-voltage Pro wiring assumption.

On a 6S aircraft, trace the actual power connection. A regulated output and the main battery pads are not equivalent. Check the flight controller's documentation and output rating before plugging a replacement transmitter into an existing cable.

Buy the matched camera/transmitter combination. DJI lists only partial O3/O4 accessory reuse and excludes the camera module and camera coaxial cable from the shared list. Compare the selected O4 Air Unit or O4 Pro variant against the frame's actual dimensions. DJI accessory compatibility guidance.

Separate the live picture from the recorded footage

Onboard camera recording is the file saved by the airborne unit. The live feed is what travels to your eyes. Goggle DVR records the received view. A 4K recording specification does not mean a 4K goggle display, and a clear onboard recording does not prove the radio link stayed clear throughout a flight.

Check each output independently: the mode you fly with, the file you intend to edit, and the recording you want for troubleshooting. Save a short clip from each enabled recorder before relying on the setup.

Video compatibility and control compatibility are separate

Choose the controller by its complete name. DJI FPV Remote Controller 2 is not the screen-equipped DJI RC 2, and an RC Motion controller supported by a DJI camera drone is not automatically a controller for your Air Unit build.

Sources: O4 control combinations, O3 support and O3/G3 controller update. The table covers Air Unit builds, not Avata or Neo control modes.

Using ELRS does not require buying a DJI controller just to obtain video. It does require a compatible ELRS receiver, correctly connected and configured on the aircraft. The same principle applies to a separate Crossfire setup. Verify the BNF receiver variant instead of assuming that an “O4 version” includes your preferred receiver.

With a DJI controller, verify the flight controller input, serial receiver configuration and SBUS settings for that board. With a separate receiver, follow that receiver's protocol and wiring instructions. Do not copy a DJI SBUS configuration into an ELRS build merely because both use O4 video.

Activate, update and link the correct combination

Remove propellers for bench setup, fit the antennas, and provide airflow around the powered Air Unit. Record the working versions and settings before changing an existing aircraft. Keep power and data cables accessible so diagnosis does not require dismantling the frame.

1. Activate each device and select the right firmware path

DJI's O4 activation instructions require the transmission module to be powered and connected to a computer by USB-C, using DJI Assistant 2 (Consumer Drones Series). A USB connection alone is not the documented O4 activation procedure. Activate the goggles through their own instructions too. Official O4 activation steps.

For current O3/O4 combinations, check the relevant release notes and update each required device, then restart. For the original Air Unit, first resolve the legacy firmware branch described above. Do not try to make all devices display the same version number: firmware numbering is device-specific.

2. Link video first, then complete the chosen control path

Select the actual Air Unit in the goggles' Status menu. For O4 with G3/N3 and FPV Remote Controller 3, DJI's example links the goggles to the Air Unit, then the goggles to the controller. Its G2/Integra and FPV Remote Controller 2 instructions instead link the controller to the Air Unit. Follow the procedure for your combination, including the correct button actions. DJI linking guide with both procedures.

If using ELRS or Crossfire, complete that radio/receiver binding separately. Then check stick movement and switch assignment in the flight controller's receiver view. Seeing the camera feed is only the video check.

Watch: DJI's O4 linking demonstration

DJI Tutorials demonstrates Goggles 3 and DJI FPV Remote Controller 3. Use the separate written steps above for G2/Integra with Controller 2. Watch on YouTube.

3. Prove the complete setup before changing extra settings

Confirm a stable picture, readable OSD and correct control inputs. Check failsafe behavior using the flight controller and receiver manufacturers' procedure. Test both recorders, then recheck mode and switch settings after updates. Change one setting at a time and keep a short configuration log for each aircraft.

No picture or no control? Isolate the failed link

DJI's March 5, 2026 O4 Pro release entry describes a fix for a black-screen issue associated with interrupted video transmission. That makes firmware history relevant, but it does not prove every black screen has that cause. Include the exact Air Unit model and version in a support request. O4 Pro release history.

Build the shopping list around the aircraft

• Keeping your headset: confirm the new Air Unit pairing, then budget for the matched camera, mount, antennas and suitable supply.
• Keeping an O3 aircraft: choose a documented O3 headset and verify the controller arrangement before changing anything airborne.
• Buying a complete aircraft: check the selected video and receiver variants, included equipment, battery requirements and whether goggles are sold separately.

Compare compatible models in digital FPV goggles, then inspect the required airborne package in digital FPV transmitters. These collections include multiple ecosystems, so verify each product's exact system.

If you prefer an assembled aircraft, browse FPV drones with DJI O4 and read the selected package contents. Keep the regional sales/service check separate from the compatibility check, especially for O4 Wide.

Frequently asked questions

Are DJI Goggles 2 and FPV Goggles V2 the same?

No. Use the complete label. They have different compatibility paths, as the main chart shows.

Can Goggles N3 receive O3?

O3 is not in the reviewed N3 support list or release history. Do not select N3 for an O3 aircraft; choose a documented O3 pairing.

Does using ELRS mean I also need a DJI controller?

No. A correctly installed independent radio receiver provides the control link. Your goggles still need to support the aircraft's DJI video unit.

Does support for Neo or Avata prove Air Unit compatibility?

No. Check the Air Unit by name. Camera-drone compatibility and control features do not transfer automatically to a custom aircraft.

Can an HDMI adapter make another headset receive DJI video?

An adapter does not decode the DJI radio link. If you also fly other systems, read our HDZero Goggle 2 receiving-path guide to understand native reception versus an external receiver. Do not assume its Walksnail VRX method applies to DJI.
