A4988 Stepper Motor Driver Carrier - StepStick
  • 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 (380k pdf) 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).
  • The equivalent to A4983-board but offers overcurrent protection. If the boards get too hot, they will interrupt the current until it cools a bit. If the current is too high for the heat sinking, the motors will pulse as the current is interrupted and restored.
 
  • 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.
 
  • A4988 Module x1
