2 Features and Specifications of ULN2003 5V Stepper Motor Driver

Stepper motor plays a prominent role in various electronic and robotic applications. 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. And, for this reason, there are many types of drivers which are available in the electronic market. This article is about the ULN2003 5-12V Stepper Motor Driver.

An Overview

This ULN2003 5V DC Stepper Motor is a small, cheap, and great-quality step motor driver. With greater stability and reliability. The module has a ULN2003 IC which is one of the most frequently used stepper Motor driver IC used when one needs to drive loads having high currents. 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.
