Good morning.

I recently bought for a ridiculous price (50 euros ...) the gimbal Movie GPX4 as "broken".

In fact, they probably have updated the firmware without first saving the settings, in fact, by resetting the motors and PID everything works.

I have photographed the cards, I have not found any information about them, but I think they are only 8 bits.

Can you tell me exactly what the cards are and maybe the pinout?
Are they 8 or 32 bits?
Can you recommend some upgrades?

The gimbal uses 2 GBM5101-12T motors for the pich, and two GBM8017-120T motors for roll and yaw.

Thank you.
