Stepper Motor Driver A4988

A 3D printer stepper motor driver A4988 is an integrated circuit designed to drive a bipolar stepper motor. It is typically used in 3D printers and other CNC machines, allowing them to move accurately and reliably. The A4988 driver is based on the Allegro A4983 microstepping driver chip and includes a fixed off-time current regulator, which has the ability to operate in slow or mixed decay modes.

The A4988 driver is capable of driving up to 1/32 microstepping and can provide up to 1.2A per winding with a maximum supply voltage of 35V. It is also equipped with a variety of protection features such as thermal shutdown, undervoltage lockout, and overcurrent protection. Additionally, it is compatible with both 3.3V and 5V logic levels, making it easy to integrate into any system.

The A4988 driver is an ideal choice for 3D printing applications due to its low cost and reliable performance. It is available in a variety of package sizes, including through-hole and surface mount, making it easy to integrate into any project.
