So I know the gimbal for the 4K, and the pro are not interchangeable, but does anyone know if the main boards on the gimbal can be swapped? I bought a 4K camera and it ended up having a dead board I believe, it doesn’t have any indication lights on that come on, but can I swap a pro main board into it? Anyone have any idea, I found the main board for the pro on a China website although a bit spendy
