A4988, Stepper Motor Driver Module – Adjustable Current, Microstepping

The module features adjustable current control via an onboard potentiometer, allowing users to set the optimal current for different motor types and power supplies. With its wide input voltage range (8V to 35V), it is versatile and compatible with a variety of projects.

Safety is a key design aspect of the A4988, with built-in protections such as thermal shutdown, overcurrent protection, and undervoltage lockout, ensuring longevity and reliability during operation. It can deliver up to 2A of current per coil, making it a powerful solution for driving high-torque stepper motors.

• Microstepping Modes: Supports full, half, quarter, eighth, and sixteenth-step resolutions.
• Adjustable Current Control: Easily fine-tune the motor current with an onboard potentiometer.
• Built-in Protections: Includes thermal shutdown, overcurrent protection, and undervoltage lockout.
• Compact Design: Small form factor ideal for integrating into space-constrained projects.
• Wide Input Voltage Range: Operates from 8V to 35V, suitable for a variety of motor applications.
• Up to 2A Per Coil: Capable of driving stepper motors with up to 2A of output current per coil.
