Features
- Easily connect up to four Unipolar Motor Driver boards to one Arduino running Grbl.
- Standard port configuration for Grbl running on an Arduino UNO.
- Optional 4th Axis enable through jumpers (requires change to configuration file).
- IDC26 connector to connect directly with DIY CNC Controller.
- Four onboard buttons for Start, Feed Hold (Pause), Abort and Reset.
- Screw terminals for connecting limit switches and E-stop, as well as Coolant enable and Spindle control. (Spindle control not available when using 4th axis).
Board Layout
The board is the same size as an Arduino UNO (or similar board).
