Pixhawk and Motor Controller

Hey guys, I was wondering if somebody can help me out with the Pixhawk 4 connection with a MODEL DBH-12V motor controller. I’m working on a rover but I’m having difficulties understand the pin connections with these two and understanding what they mean. Can somebody help me out? It would be much appreciated. Plus, if anybody knows how to, i want to test the motor and make sure that wheels can turn and move, if anybody can show me how to do that im currently working with ROS and im a complete beginner.

Thank you guys :slight_smile:
