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

Product Features

  • Uses removable A4988 or DRV8825 compatible stepper drivers. The extension board can be used for carving machine, 3D printer driver expansion board. GRBL 0.8 compatible. (Open source firmware that runs on an for arduino UNO that turns G-code commands into stepper signals)
  • PWM Spindle and direction pins,4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
  • Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use.
  • Parameters : dir direction control , dirPin corresponding stepper motor DIR pin , stepperPin corresponding stepper motor ” step ” pin , Step number of step of no return value.
  • void step (boolean dir, byte dirPin, byte stepperPin, int steps); digitalWrite (dirPin, dir); delay (50); for (int i = 0; i Less Than steps; i + +); digitalWrite (stepperPin, HIGH); delayMicroseconds (800); digitalWrite (stepperPin, LOW); delayMicroseconds (800);
