DJI O3 Air Unit User Manual
Use glue or screws to install the transmission module. If using screws for installation, remove the four M1.6 x L6 mm screws on either side of the module. Install the module on a racing drone or other device with the screws.
M1.6 x L6 mm
There are four M2 × L4 mm screws attached to both sides of the camera module (the depth of the screw hole is 2 mm). Remove the screws and use them to mount the camera to the aircraft frame if the thickness of the aircraft frame is between 23 mm. Adjust the camera to an appropriate angle based on your requirements when installing.

M2 x L4 mm

Choose the screw length carefully when installing the camera module. The length of the screw should not exceed the sum of the screw hole depth (2 mm) and the thickness of the aircraft frame. If the screw is too short, the camera module may not be securely fastened. If the screw is too long, it may cause damage to the internal structure.
To obtain the optimal transmission, keep the antenna away from any metal or carbon fiber structures, and make sure that the antenna is not blocked by any frame structures.

3-in-1 Cable
Connect the 3-in-1 cable to the 3-in-1 port on the air unit. Refer to the diagram below to solder the other end of the cable to the flight controller. An electric soldering iron and soldering tin are required for connection. Make sure that there are no short circuits or open circuits when soldering the cables.

Important Notice and Installation Guidelines DJI O3 Air Unit Installation Method and Cooling Effect
DJI O3 Air Unit is integrated with both the image transmission module and the camera module. Compared with the last generation DJI Digital FPV System, the size of DJI O3 Air Unit is reduced by 40%, while the power consumption is increased by 40%. Restricted by its cooling condition, extra ventilation and heat dissipation measures are necessary when installing the air unit. Standby Time (from cold start):
Environment temperature 25° C (77° F): 8 mins Environment temperature 35° C (95° F): 5 mins
When installing the DJI O3 Air Unit, make sure that the RX and TX pins are correctly connected to the flight control board. The air unit can apply different temperature control strategies for the standby and flight states. [1] [1] DJI O3 Air Unit has two sets of temperature control strategies for the standby state and the flight state: In the standby state, the protection system will be activated to automatically shut down the air unit after overheating. In the flight state, there will be a prompt alert after overheating and the video recording will end. At this time, the video transmission will remain connected and the aircraft must return and land within 30 seconds. If the temperature of the internal IC board continues to rise, the protection system will be activated to shut down the air unit automatically.
Installation Guidelines Recommended installation practices that are effective for ventilation and heat dissipation:
It is recommended to mount the air unit in a position close to the propellers (distance between the air unit module and the propellers within 10 mm) so that the downwash can be effectively utilized. Use a heat conductive material to connect the aircraft frame and the air unit module. This will dissipate heat to the carbon plate and other metal components of the frame. Conducting the heat will extend the operating time. DO NOT install the air unit in an enclosed area.
The metal casing of the DJI O3 Air Unit will become hot after being powered on. The air unit should not be installed in a position that is easily accessible.

DJI O3 Air Unit User Manual
Video Image Shakes After Enabling RockSteady Mechanical vibration at certain frequencies may result in abnormal EIS (electronic image stabilization) performance of the DJITM O3 Air Unit.
Cause IMU Resonance
The usual ESC (electronic speed control) PWM (pulse-width modulation) control frequency is 24 kHz by default, and the camera IMU frequency is around 24 to 30 kHz. If there is no effective vibration absorbing measure, the motor vibration may be transmitted to the camera IMU, causing resonance because the frequencies coincide. The resonance will affect the IMU data accuracy and EIS performance of the video stabilization application.[2] As a result, the processed video image shakes, but the liveview image is not affected. Usually, aircraft frames with TPU or vibration absorbing rubber are not prone to the IMU resonance issue.
[2] Video stabilization application: refers to either the DJI O3 Air Unit EIS function or a third-party video stabilization software.
Rolling Shutter Effect If the rolling shutter effect appears in both the liveview and the video image, it is usually because the propeller vibration (frequency is around a few hundred Hz) is transmitted to the camera through the aircraft frame.
Troubleshooting and Tuning Guide Follow the steps below to troubleshoot and fix the image stabilization issue: Step 1: rule out the IMU resonance issue 1. Remove the propellers from the aircraft. Make sure that the camera is securely mounted and the
aircraft is placed stationary on the ground. Then enable RockSteady and start recording. 2. Start the motors and slowly push the throttle to the full position. Observe the liveview in the
goggles. If the liveview is not shaking, stop the motors and end the recording. Otherwise, check the camera and make sure it is securely mounted. 3. Check the recorded video. If the video image shakes, the issue is most likely caused by the resonance between the frame and the camera IMU. In this case, refer to the following solutions: Solutions a. Change the ESC PWM control frequency to 48 kHz or 96 kHz and test again. b. If the video image shakes after the solution (a) is adopted, apply a softer vibration absorbing
structure between the camera and the aircraft frame. Repeat the above testing procedures until the video image does not shake.
Step 2: rule out the rolling shutter effect issue After ruling out the IMU resonance issue, check if the video image has the rolling shutter effect. 1. Install the propellers on the aircraft and make sure that the propellers are not damaged. 2. Fly the aircraft and start recording with RockSteady enabled. Check the video image after the
flight. If the video image has a rolling shutter effect, try the following solutions: a. Adjust the vibration absorbing structure between the camera and the aircraft frame again. b. Adjust the tightness of the screws that fasten the camera to the aircraft frame.
If the issue still exists after all the above methods are completed, contact DJI for support.
