Antenna Rotor V3.0.1 - Where does the Arduino Board reside?

I just shot you a email with what I have figured out. I still dont know what pins on the raspberry connects to the satnogs controller, and also what the startup procedures are with and without the raspberry pi connected. Is the rotator supposed to home or anything first? Lots of questions and little answers. I also asked how you download and install the PI image (I’m a PI Noob)
