DJI Air 2 Core Mainboard with Vision Components & Fan

A Mavic Air 2 that has been through a crash or a dunking can show several faults at once: system errors at startup, vision warnings and a fan that won't spin. Chasing each one separately can cost more time than the drone is worth, which is why some technicians replace the core of the aircraft as one assembly.

This kit, listed for the DJI Mavic Air 2, combines the mainboard with front and downward vision sensors and the cooling fan. The listing doesn't state DJI origin, so it's sold as aftermarket.

Faults that point to the Air 2 core board

• Persistent system or flight-controller errors after a crash.

• Vision sensor errors that remain after cleaning the sensors.

• Overheating warnings or a fan that stays silent.

• Corrosion on the board after water exposure.

Plan for setup work

The listing notes that some drone parts need a programmer or software calibration after replacement. Expect the vision sensors to need calibrating, and confirm how your drone will be activated and paired before you start. Photograph cable routing, keep ribbon connectors clean and test hover, sensors and camera before the first real flight.

It's a big-ticket part, so it's the right call when several systems have failed together rather than when one sensor alone is at fault.
