A4988 Stepper Motor Driver

The A4988 Stepper Motor Driver is a compact electronic module used to control bipolar stepper motors with a microcontroller such as an Arduino UNO or Arduino Mega. It allows precise control of the motor's direction and movement and supports different microstepping modes for smoother and more accurate motion. The A4988 is commonly used in 3D printers, CNC machines, robotic systems, camera sliders, and other STEAM projects that require controlled stepper motor movement. It uses STEP and DIR signals from the microcontroller to control the motor and has an adjustable current limit to help protect the motor and driver.
