Arduino CNC Shield V3

Arduino CNC Shield V3

This expansion board as a driver expansion board can be used for engraving machines, 3D printers. 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. It is very convenient to use.


  • Enlarged board to add a 4th Axis that can clone the X, Y, or Z-axis. With a 4th option to use pin D12-13 to control it.
  • Added a breakout header for all the Axis’s
  • Added a communication header for UART(Serail) and I2C
  • Added a connector for an optional fuse. (Fuse not supplies as it needs to be selected for the current that will be used.)
  • Capacitors are mounted horizontally giving more clearance between them and the stepper drivers. Good for ventilation.
  • Added a pull-up resistor on the axis enable pins. This prevents the pin from being in a floating state
  • Added 2 mounting holes
