DJI mini 1 and 2 gimbal details

[Dula]

Good morning. I'd like to ask if anyone knows the details of how the gimbal on the Mini 1 and 2 works. Specifically, it has an IMU next to the camera sensor, but maybe it has magnetometers next to each servo. Could someone provide detailed information?

My question is because some of the servos are vibrating and buzzing after being repaired. I'd like to know how to rule out the PTZ cable. Does anyone have a diagram for checking this cable?

Lastly, if anyone could send the software to clear error 40021, etc., I would be very grateful.

Thank you

The gimbal does not use magnetometers It uses brushless motors that are controlled by the IMU. That buzzing sound you are hearing is because your PTZ cable is damaged or not seated or installed incorrectly -- Believe me its a common "tell".
There is no "work-around" for the 40021 error and that error would show up if you had a bad or miss-installed cable. Purchase a new cable and carefully install it..Dont forget to replace any silicone or heat paste you remove! this is most important!
P.S. ONLY USE KINGBOXER silicone on your Drone NOTHING from the hardware store! (kingboxer DX-704)
