Features

Expansion Board Pin-out Definition:

  • 8 ----------------------- EN ( stepper motor driver enable, active low )
  • 7 ----------------------- Z.DIR (Z -axis direction control )
  • 6 ----------------------- Y.DIR (Y -axis direction control )
  • 5 ----------------------- X.DIR (X -axis direction control )
  • 4 ---------------------- Z.STEP (Z -axis stepper control )
  • 3 ---------------------- Y.STEP (Y -axis stepper control )
  • 2 ---------------------- X.STEP (X -axis stepper control )
    • GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
    • 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)

    • 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.)
