A4988 Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap, CNC Machine or Robotics

Key Features

• Simple step and direction control interface,Take anti-static measures before you use the A4988 modules in case of short-circuit
• 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
• 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
