The Keyestudio ULN2003 Stepper Motor Driver provides accurate control of stepper motors through an open-loop system, removing the necessity for expensive feedback components such as optical encoders. It determines motor position precisely by monitoring input step pulses, streamlining design and minimizing system complexity. Included with the driver is a 5V stepper motor, allowing you to begin integrating it into your projects immediately without needing extra parts.
