GimbalCtrl Interface

  • item number: GIMBALCTRL

This is control board for controlling Brushless Camera Gimbals (for AlexMos Hardware)

The gibmal is directly controled via data bus, so no additional servo channels are necessary.
The current angles of the gimbal are read and recorded in the log files. As a result, in postprocessing, e.g. the inclination of the gimbal can be assigned to the corresponding photo.
The GimbalCtrl is connected via I2C plug connection to a FlightCtrl V3.0. If this is connection is already in use by other hardware, then an I2C bus splitter can be used.
The interface is connected to the AlexMos controller with 3 lines (RxD, TxD, GND). The cables must be connected according to the AlexMos hardware.

There are also 3 special outputs available on the interface: OUT1 & OUT2 are general purpose outputs that can be assign to e.g. a RC channel in KopterTool. For example to switch between display modes of a special IR camera.
OUT3 is a mapping of the normal photo trigger output to connect a shuttercable.
So you can control a lot of features using only a few I2C lines. This makes it a lot easier to connect gimbal and cameras (less wires).

The outouts are only available as solder pins. Connecting has to be done by the customer.
