A4988 Stepper Motor Driver (Original)

Description:

This breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow.

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. This stepper motor driver lets you control onebipolar stepper motor at up to 2 A output current per coil (see the Power Dissipation Considerations section below for more information)

Features:

  • Minimum operating voltage: 8 V
  • Maximum operating voltage: 35 V
  • Continuous current per phase: 1 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
  • Bulk packaged: N
  • Header pins soldered: N4
