Because the step angle is only half of the 1.8 °stepper motor, the 0.9 °stepper motor has a higher resolution and smoother operation. The driver of 0.9° stepper motor and of 1.8° stepper motor are exactly the same. An example of a good application for 0.9°motors are security cameras 0.9 °stepper motor can make the camera operating smoothly and accurately, which avoid the situations that causing the camera shaking that results in the image blur.
