Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step * Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor"s rated voltage to achieve higher step rates * 45 V maximum supply voltage * Built-in regulator (no external logic voltage supply needed) * Can interface directly with 3.3 V and 5 V systems
