what is voltage rating on this motor? Looking for 3.4V 2.8A stepper

Coil voltage is 3.4V, the driving voltage is 24-48V.

Do you also provide the screws that can be used to mount the stepper motor?

Sorry, we don't provide screws for the mount currently.

Can i vary the steps of travel with an external pot input on this controller?

No. You question us confusing since this is a motor not a controller. This motor has a fixed step of 1.8 degrees you can’t change that from the controller. Not sure what you’re trying to do but you may want to look into a servo motor

Can an encoder be attached to the back of the motor?

There are no features on the back of the motor that would allow the mounting of an encoder.
