It would be different for OpenGrade X,  
but for OpenGrade and OpenGrade3D:

First you need a GPS receiver connected trough **USB**. With this you can use all feature but the automatic valve control.  
The standard Ardusimple F9P is a good choice.

The valve control is connected trough a second USB port with an Arduino nano. For the PCB I recommend the Original V2 or the Kaupoi. Put a cytron, a little joystick and some indicators lights.

There is also an option to use the CaseIH/John Deere auxiliary valve but I don’t know much about it, more info [here (grade control, post 426 and up)](https://discourse.agopengps.com/t/grade-control/1702/426)

I just use one of these cheap ones. Really any analogic 0-5v one works.
