This is main board normally put on Gimbal frame near the Quad . 

This is the two options imu available normally is on camera module: 

2 axis with 3 accelerometer and 3 gyroscope 3 magnetometer in one version we use mpu6050 and in other we use mpu 9150 1 chip 9 DOF sensor.

Some friends start to design different kind of gimbal for our new board. The main difference respect of standard gimbal is that the mechanical frame need to be develop for each video sensor that you would like to use for your video. This frame is for Gopro Hero 2-3 in the design is important to move CG of camera for obtain better result during gimbal stabilization :)

This is the caratheristics of our : VR Gimbal :

Micro Controller is STM32F1 at 72 mhz.

3 Axis Brushless Direct Drive gimbal :

• Roll    (MOT1)
• Pitch  (MOT2)
• Yaw    (MOT3)

For each channel we have 3 high power pwm output .

I2C IMU that support 3 axis . It  is on camera module , so we can know exactly the position of camera and control in realtime the 3 Brushless motors.

We are developing two option :

• more traditional approach : MPU6050 (6 DOF) + HMC5883 (3 DOF)
• new sensor from inversense MPU 9150 (9 DOF)

1 USB port.

1 Serial port that support mavlink protocol.

1 Power module that support until 3S battery.

4 Radio RC Input for :

• Control ROLL Setup.
• Control Pitch Setup.
• Control YAW Setup.
• IR control repeater.

4 Analog Input 0-3.3v

1 IR Out , so is pssible to control a remote camera by its ir receiver.

The first batch of production will be available in 3 week it's better to reserve your board because there is a big request of this gimbal.
