The A4988 driver is a module for controlling bipolar stepper motors with microstepping up to 1/16 step, supporting voltages up to 35 V and currents up to 2 A. It is used in 3D printers, CNC machines, and projects requiring precise motion control.
Description
The A4988 module is a popular bipolar stepper motor driver designed for use in 3D printers, CNC machines, and other devices requiring precise motion control. It supports full-step and microstepping modes: 1/2, 1/4, 1/8, and 1/16 step, allowing smooth and quiet motor operation. The driver handles supply voltages up to 35 V and currents up to 2 A (with proper cooling). With its simple STEP/DIR interface, it can be easily controlled by microcontrollers such as Arduino. The module includes current adjustment via a potentiometer, as well as thermal shutdown, over-current, and short-circuit protection.
