What device should I use?

DudeMcLovin:
Not sure if this qualifies as a data sheet, but here we go.

In your Original Post you said

I have a borad through which I can control two nema steppers with joystick modules

but when I look at the link in Reply #16 I can't see any information about how you can connect joysticks to the "Smoothieboard"

Can you explain it?
