VR GIMBAL : 3 Axis 32bit Direct Drive Gimbal is coming !

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.

That's beauty, Roberto!  You guys nailed it.  I'd love to see how this compares to alexmos board. :)

Hi Motomoto, 

in last revision of pcb we improve the hardware capability and now is possible to use until 30v 5-6s without problem , also the first batch of board if necessary could be upgrade to manage safe 30v input. The new board will be available in the mid of august ... in some days we reopen the pre order. All the board order in first stock sent and some first video from user is present in our media gallery.

Supports up to 3S battery seems a bit lacking.. for heavier payloads like large DSLR or RED cameras , min. 4S battery is recommended.

The below images are my latest Brushless system based on a Viacopter board. The gimbal features an inner axis with will move only 2 degree for the fine tuning and will be drive by small voice coil actuators .

The camera shown has a full zoom equivalent of 480 mm in 35 mm terms.  The wind guard is essential.

I do think that 6s or even 12s would be more sensible as it simplifies the power sourcing.

Hello , 

I see that the board support until 3s battery.

Is it not a bit less . The Alex Mos support till 6s I think .  And the brushless drivers support that too.

For brushless torque motor normally you use hi voltage to have a maximum of torque with a current limited to 3 or 4 Amps.

Best, 

Sandra
