Nvidia Jetson TX 1 information and advice

Hello Everyone,
I am about to start an project and I am thinking of using PixHawk with Nvidia Jetson TX1. As I am new to it , I am little confused with the decision. I have worked with Pi so I know which all sensors I can use. But I do not find information about sensors compatible with Jetson TX1. And I read about Pixhawk and TX1 connection , I am little confused so as to is it necessary to have that carrier board(Can you please tell me what its function is).
