OpenROV IMU/Compass/Depth Module

This is an open-source, low-cost sensor module that enables highly accurate depth, compass heading, roll, and pitch to be overlaid on the camera stream in the OpenROV cockpit. Having this additional telemetry will greatly help with navigation, gathering relevant scientific data, and allows for closed-loop control commands that will make the OpenROV much easier to fly such as compass heading hold and depth hold. This module is added to the I2C auxiliary wires and can be integrated either during the build process or after the build is completed. 

This product requires some assembly, including: Acrylic solvent cement, soldering and epoxy. Please see assembly instructions for more information about the assembly of this product.
