Overview

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 (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key 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
4-layer, 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad below the driver IC on the bottom of the PCB

This product ships with all surface-mount components—including the A4988 driver IC—installed as shown in the product picture.

The Black Edition has the same component layout and pinout as our A4988 stepper motor driver carrier, so it can be used as a higher-performance drop-in replacement in applications designed for our original drivers. The Black Edition achieves its higher performance through its four-layer printed circuit board (PCB), which better draws heat out of the A4988 driver—while our original carrier can deliver up to approximately 1 A per phase in full-step mode without a heat sink or air flow, the Black Edition can deliver up to approximately 1.2 A under the same conditions. (For an even higher-performance alternative, please consider our DRV8825 stepper motor driver carrier, which can deliver more current over a wider voltage range and can be used as a drop-in replacement for the Black Edition in many applications.)
