DJI Mini 2 Main Board Replacement

Введение

This guide will show you how to successfully replace the main board inside the DJI Mini 2 drone.

The main board in the DJI Mini 2 helps the drone tell the other parts of the drone what to do and connects the controller and phone connected to the drone. If the main board is damaged the drone will not function or connect to the controller and phone the user wants to connect to. For more information on what may be causing your issue, check out the Troubleshooting page for this device.

After replacing the motherboard, you will need to calibrate your DJI Mini 2 drone. Some calibration processes can be done with the DJI Fly mobile app, but for some processes, like gimbal calibration, you will need to use additional software.
