Product Features

  • – It is a flexible set, with 3 axis stepper motor driver, compatible with Arduino and most shields designed for the Arduino micro-drive laser engraving machine, three-axis CNC engraving machine
  • – Power DC5V interface and 7.5-12V voltage input, compatible with GRBL for easy service, part replacement, upgrade-ability and expansion
  • – Easy to operate: 2A can be controlled within the two-phase four-wire stepper motor, simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started
  • – Released the digital IO interface and the I2C interface, easy to connect to other modules, such as ENDSTOP, LCD I2C or other I2C module
  • – Simple step and direction control interface, taking anti-static measures before you use the A4988 modules in case of short-circuit
