CNC Shield Board + 4Pcs A4988 Stepper Motor Driver For Arduino 3D Printer


CNC Shield Board:

  • Version: 3.0
  • Color: Red
  • Size (L*W*H): 68 x 53 x 18 mm
  • Voltage: DC 12~36 V (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)


  • Uses removable A4988 or DRV8825 compatible stepper drivers.
  • The extension board can be used for carving machine, 3 d printer driver expansion board
  • GRBL 0.8 compatible. (Open source firmware that runs on an 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.
  • Please note that this is an unassembled kit and Basic soldering skills are needed.
