A4988 Stepper Motor Driver Module for Velleman 3D Printer


Part Number: VUPN7947

manufacturer: Velleman
manufacturer part number: A4988/SP

The A4988 Stepper Motor Driver Module is the most popular stepper motor driver for 3D printing. The A4988 Motor Driver IC is soldered on to a carrier board along with the associated SMD components. The carrier board has 2 x 8-Pin single row headers soldered to it - it is ready to be dropped into your RAMPS, Sanguinololu, or other compatible controller board. A small SMD potentiometer provides current adjustment capability.

Most 3D printers require 4 of these modules.


  • Simple step and direction control interface
  • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
  • Adjustable current control - set the maximum current output with a potentiometer, which lets you use voltages above your stepper motorís rated voltage for 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
