3.1 VDC STEPPER MOTOR

In my testing with a sn754410, pin numbers to colors are: 1 yellow, 2 black, 3 red, 4 gray.

This particular stepper does not exactly match what I have. My old model is 15 degree, 24 steps, and weighs just under 1 lb at 450gm vs
454 gm/lb. Four questions: (1) will this unit work fast or slow ref. 7.5 deg vs 15 deg. (2) does this unit have a Holding Torque at 0.7 ,(3)
Told the " EasyDriver " would work for my old unit ... this one however ? (4) does this unit weigh in ~ around one pound, roughly ?

You can drive this with a dual full-bridge driver, like the ST L298 and a controller chip like the ST L297/1. It's easy, only three control inputs on the L297, a clock input and then just switch the direction and enable inputs.

Does anyone have any info on this, IE what it needs and how to hook it up?
