The board also includes a connector thatch makes it very easy to connect the motor to the module board.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. For example, digital logic circuits, Timers, Gates, etc. 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.This article is about the ULN2003 5-12V Stepper Motor Driver. And, for this reason, there are many types of drivers which are available in the electronic market. But, these motors require a driver circuit. These motors may run at high speeds but have a high holding torque. For example, in robotics arms, antennas, telescopes, etc. We use the stepper motor for correct positioning in different circuits. Stepper motor plays a prominent role in various electronic and robotic applications.
