Martinez V3 Brushless Gimbal for GoPro Hero3

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.





Preparing the board.

- the wire for power soldered directly to the board with JST connector at one end (power taken from the on board 3s battery).
- pin headers for both gimbals motors, sensor connection and A1 pin for tilt control.
- A1 pin is fed with a signal wire from one of the free channel to control tilt. Red (+) and Black (-) wire don't need to be connected.
- wires from an old computer mouse were used for the sensor for it is flexibility and it won't fight the gimbals plate movement.

Firmware

The best and easiest setting to get are from Brugi_049_r161. When you extracted the downloaded file, you will find the Brushless Gimbal Tool and 3 picture of typical settings for GoPro in the GUI folder.

The Settings

Have to make sure the GoPro are set balance on the gimbal tray first before powering the board up for any settings.

This is the setting that i used. It might not work for your setup.

This is my test rig for setting up the gimbals. Taken from my previous twincopter - http://www.youtube.com/watch?v=7FXeSqEm9co

Mounting The Gimbals

On my DIY tricopter I am using the technique from rcexplorer.se of vibration dampening.
