To choose a motor driver you need to take into account the specs of your motor, this guide will help you with that
Is the motor you selected unipolar or bipolar? Choose a stepper motor controller type accordingly, though a growing number are able to control both types. The number of leads is usually a dead give-away of the motor type: if the motor has 4 leads, then it is bipolar; should it have 6 or more leads, then it is unipolar.
Choose the motor controller voltage range to match your motor’s nominal voltage .
Find out how much current percoilyour motor requires, and find out how much current (per coil) the stepper motor controller can provide.If you cannot find the current per coil, most manufacturers list the coil impedance, R . Using Ohms Law (V=IR), you can then calculate the current (I).
As with DC motor controllers, the control method is an important consideration.
The G203V Digital Stepper Motor Driver has these ratings:
Power Rating: 80VDC, 7A maximum
So you will probably need at least that.
I couldn’t find the “microstepper gecko drive” you mentioned, could you please share the product code?
