Description:
The Pololu 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 version. Like our original carrier, the Black Edition offers adjustable current limiting, overcurrent protection, and five different microstep resolutions. It operates from 8 – 35 V and can deliver up to 2 A per coil with sufficient additional cooling. 

Specification:

  • Minimum operating voltage: 8 V
  • Maximum operating voltage: 35 V
  • Continuous current per phase: 1.2 A2
  • Maximum current per phase: 2 A3
  • 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
     

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 protection
