Hello, I can confirm the statement by Gruppetto-joe.

On the image:

it is easy to see that the integrated USB port in the head of the gimbal could not be connected because the water-repellent protective flap gets in the way.

i doubt it, since the gimbal is designed for the gopro4 and the gopro5 has a rubberised (waterproof) housing.
