The Green A4988 Driver Stepper Motor Driver – Standard Quality is a reliable and versatile motion control module designed to drive bipolar stepper motors in robotics, CNC machines, 3D printers, automated positioning systems, and custom mechatronics projects.
At its core is the popular A4988 stepper driver IC, which enables up to 1/16 microstepping, providing smooth and accurate motor motion with fine resolution. The module supports operation across a wide voltage range (8V to 35V DC) and can deliver up to 2A per coil (with proper cooling) to the connected motor — ideal for small to medium stepper motor applications.
The compact form factor and easy-to-use interface make this driver module ideal for hobbyists, engineers, and makers. With dedicated STEP and DIR control pins, it interfaces seamlessly with popular microcontrollers like Arduino, ESP32, Raspberry Pi, STM32, and others. Adjustable current limiting allows you to configure motor drive current precisely, ensuring optimal torque while preventing overheating.
Built-in protections such as over-current limiting, thermal shutdown, and under- voltage lockout help ensure reliable long-term operation even under demanding conditions.
Whether you’re building a custom CNC rig, robotic arm, or automated stage, this A4988 driver module offers precise control and dependable performance for your motion control applications.
