Rajiekart A4988 Compatible Stepper Motor Diver Module with Heat Sink for 3D Printer Controller


  • 4988 driver board widely used in 3D printers and small CNC machines.
  • Simple step and direction control interface.
  • Thermal protection, over-current protection, ground fault protection.
  • 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 toachieve higher step rates.
