We use the stepper motor for correct positioning in different circuits. For example, in robotics arms, antennas, telescopes, etc. These motors may run at high speeds but have a high holding torque. But, these motors require a driver circuit.
The module comprises ULN2003 IC which is one of the most frequently used stepper Motor driver IC used when one needs to drive the loads having high current. For example, digital logic circuits, Timers, Gates, etc. Since some motors that require 9V and 300mA to run cannot be powered by the microcontroller and therefore we use this IC to source enough current and voltage for the load.
The board also includes a connector that makes it very easy to connect the motor to the module board. Moreover, there are connections for four control inputs and power supply connections.
The board has four LEDs that indicate the work on the four control input lines.

Robotics Robots usually use stepper motors in robotic arms, etc, which requires high precision. Hence, driver modules play an important part there.
3D Printers Stepper motors are an essential part of 3D printers. We use them in a variety of applications depending on the type of printer.
Medical equipment
Gaming machines
Automation circuits
CNC machines, etc.
