About stepper motors

A4988 Stepper Motor Driver Module is listed under Stepper Motors — nema-frame steppers, geared steppers and driver modules. Stepper motors are brushless DC electric motors that divide a full rotation into a number of discrete steps, allowing for precise position control without a feedback system. They are commonly used in applications requiring accurate positioning, such as 3D printers, CNC machines, and robotics.
