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);

Scanner ZUM Expansion Board with A4988 Motor Driver Module For Ciclop 3D Printer DIY Printer Accessories

A4988 driver is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. It includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the “step” input inputting one pulse drives the motor one micro step. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption.
