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 with a heat sink and fan cooling.

Note: Heat sink sold separately.  Not required for current settings below 1A.

These drivers feature a 4-layer PCB with thermal vias placed under the driver chip.  This helps to ensure the best possible heat dissipation from the chip. 

Features:

    * Short-to-ground and shorted-load protection

    * Adjustable current control

    * Intelligent chopping control

    * Over-temperature thermal shutdown

    * Under-voltage lockout

    * Crossover-current protection

    * Simple step and direction control interface

    * Full-step, Half-step, Quarter-step, Eighth-step, and Sixteenth-step
