Stepper Motor Driver – a4988

The a4988 stepper motor driver is a versatile and reliable module designed to control bipolar stepper motors. It provides a simple and efficient way to drive stepper motors with up to 2A per coil. With its adjustable current control and microstepping capabilities, this driver allows for smooth and precise movements. It features a built-in translator that simplifies the interface with microcontrollers by converting step and direction signals into motor control signals. The a4988 also incorporates thermal shutdown protection, overcurrent protection, and reverse-voltage protection to ensure the safety and longevity of the motor and driver. Its compact size and easy-to-use design make it suitable for a wide range of applications such as 3D printers, CNC machines, and robotic systems.
