The stepper motor driver A4988 is used to control stepper motors that are used in 3D printers, CNC machines and any similar machinery. It provides a simple step and direction control interface and it has five different step resolutions: full step, half step, quarter step, eighth step, and sixteenth step. Also it has an adjustable current control lets you set the maximum current output using a potentiometer which allows you to use voltage above what your stepper motor’s rated voltage in order to achieve higher step rates.


  • Over temperature shutdown
  • Over current protection
  • under voltage lockout
  • Short to ground and shorted load protection

Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
