- A stepper driver is an electronic device which changes the current into the pulse.
- It actually does nothing on its own, it needs to be used with a controller.
- The basic function of a stepper driver is to drive the motor.
### Why a Stepper Motor Driver is needed?
---
- The voltage and the current required by the motor are not from the controller.
- The stepper driver could transform the movement instructions into the sequences.
- The sequences will be fed into the winding of unipolar step motor to make the motor run.
### Types of Stepper Motor Drivers:

These drivers are implemented by using the most modern technology. They are easy to use and can be effectively used for driving 2-phase or 4-phase motors. Some digital stepper driver can work with a voltage of 24-70 VDC and it maximum current can reach 10.0 A. And you can use DIP switch to set the required current and micro-steps resolution.

Some features of the digital stepper drivers you may concern:
1. Anti-resonance.
2. The motor movement will become smooth.
3. Low heat and noise.
4. Support multi-axis control
5. The micro-step resolution is selectable.
6. Support Over-current protection and Over-voltage protection.
