A4988 3D Printer Reprap Stepper Motor Driver[ROB-00041]products model : ROB-00041

This product is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

We also sell a larger version of the A4988 carrier that has reverse power protection on the main power input and built-in 5 V and 3.3 V voltage regulators that eliminate the need for separate logic and motor supplies.

Features:

• Simple step and direction control interface             
• Full-step, Half-step, Quarter-step, Eighth-step, and Sixteenth-step                     
• Adjustable current control                     
• Intelligent chopping control                     
• Over-temperature thermal shutdown                     
• Under-voltage lockout                     
• Crossover-current protection                     
• Short-to-ground and shorted-load protectio
