Includes Heat Sink and Akasa thermal tape.

Genuine Pololu A4988 Stepper Motor Driver.  This is the standard for RAMPS 1.4 & Arduino stepper motor control.  They have been widely adopted as a RepRap open hardware solution for MendelMax, Prusa, Rostock, and many other 3D printers.

Here are some of the driver’s key features:

  • 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

Pins require soldering.
