...using this 4.0A controller via an Arduino Uno?
PWM chopper type bipolar stepper motor driver IC
1. 9V-42V DC power supply
2. H bridge bipolar constant phase flow drive
3. the maximum 4.0A of the eight kinds of output current
4. the largest 32 subdivision of the 6 models are optional
5. input signal high speed photoelectric isolation
6. common-anode standard single pulse interface
7. offline to maintain the function
8. semi closed enclosure can be adapted to a more stringent environment
9. to provide energy-saving semi-automatic current lock function
10. built-in temperature protection and over current protection.
Can control 2 phase stepper motor forward and reverse rotation, With 1-2, W1 -2 , 2W1 -2,
4W1 -2 phase excitation mode.
Only the clock pulse signal can be driven two-phase bipolar stepper motor to achieve low
vibration, high efficiency work.

It's for a window auto-closer, so it will only run for a maximum of about 15 seconds, a few times a day. I don't know how much torque will be required - but using my digital luggage scales, it registered about 5kg to pull the window shut, over a distance of up to 60cm.
