Pololu's Black Edition A4988 stepper motor driver carrier is a higher-performance drop-in replacement for the original A4988 stepper motor driver carrier. It features a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer (green) version.

This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

A4988 Stepper Motor Driver Carrier, Black Edition

The Black Edition offers adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions. It operates from 8 V to 35 V and can deliver up to 2 A per coil with sufficient additional cooling. This board ships with 0.1″ male header pins included but not soldered in.

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 (1MB pdf) before using this product.

  • 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

Specification:

  • Minimum operating voltage: 8 V
  • Maximum operating voltage: 35 V
  • Continuous current per phase: 1.2 A (withut a heat sink or forced air flow)
  • Maximum current per phase: 2 A (with additional cooling)
  • Minimum logic voltage: 3 V
  • Maximum logic voltage: 5.5 V
  • Microstep resolutions: full, 1/2, 1/4, 1/8, and 1/16
  • Reverse voltage protection?: N
  • Bulk packaged: N
  • Header pins soldered: N (Male header pins are included, but not installed)
