This CNC shield V3 is used as a driving shield for engraving machines, fully compatible with UNO R3. So you just need to stack it onto the UNO R3 control board.
It has a total of 4-way pin slots for stepper motor drive modules to drive 4-channel stepper motors.
Each stepper motor only needs 2 IO ports, so 8 IO ports are enough to manage 4 stepper motors, very easy to use. This shield can make quick work for managing stepper motors in your project


  • Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others) (Not Included)
  • Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
  • Compact design.
  • Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
  • Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
  • GRBL 0.9 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)
  • 2 x End stops for each axis (6 in total)
