Helping a friend with his brushless gimbals controller is quite an interesting experience. The board came with pin headers not yet soldered to it place. Searching the internet for information regarding how to connect and how to setup the gimbals itself is a challenge. But i managed at the end to get the right settings for used with a GoPro Hero3 on board. For a new technology, brushless gimbals has come to the point where every one can have a great stable aerial videos.
I am not going for the detail step, but just sharing what i've done.
