Grab'eM A4988 Stepper Motor Driver(Blue)

This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; 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. Features:• Simple step and direction control interface• Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step• Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates• Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)• Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection• Short-to-ground and shorted-load protection• This product ships with all surface-mount components—including the A4988 driver IC—installed as shown in the product picture.This product ships individually packaged with 0.1″ male header pins included but not soldered in; we also carry a version with male header pins already soldered in. For customers interested in higher volumes at lower unit costs, we offer a bulk-packaged version without header pins and a bulk-packaged version with header pins installed.
