DJI Air 3 IMU Module with Cable

Every hover a DJI Air 3 holds depends on a small sensor package that most pilots never think about. The inertial measurement unit, or IMU, measures acceleration and rotation hundreds of times a second, and the flight controller uses that data to keep the drone level and steady.

This IMU module with its connecting cable is listed for the DJI Air 3. The listing doesn't name DJI as the maker, so it's offered as an aftermarket part.

When the Air 3 IMU is suspect

• IMU errors or repeated calibration prompts in DJI Fly.

• Drift or tilting in a calm hover that recalibration doesn't fix.

• Faults that started after a crash or a hard landing.

• A damaged or kinked IMU cable.

Calibrate before you replace

Many IMU warnings clear after a calibration on a flat, level surface away from heat, so run that first and let the drone reach room temperature. If errors return, replace the module, mount it exactly as the original sat, and calibrate the IMU again before a low test hover.

A healthy IMU is what makes the Air 3 feel locked in place in the air, so it's worth getting right.
