A4988 Driver

The A4988 is a compact microstepping stepper motor driver designed for smooth and precise motion control. It is widely used in 3D printers, CNC machines, and robotics. This driver supports full, half, quarter, eighth, and sixteenth step resolutions, allowing for fine motor movements. The built-in translator simplifies control, requiring only step and direction inputs. With adjustable current limiting, the A4988 allows you to set motor current for optimal performance. Over-temperature and short-circuit protection ensure safe and reliable operation. It works with bipolar stepper motors and operates at 8V to 35V input voltage, making it a versatile choice for various applications. The A4988 supports microstepping for smoother motion and higher resolution. It includes adjustable current control to protect the motor and driver. The thermal shutdown and overcurrent protection prevent damage from overheating. Easy step and direction control simplify integration with microcontrollers. Compatible with Arduino and other controllers, it is widely used in DIY and industrial projects.
