gShield

The Arduino gShield (formerly known as grblShield) is a complete hardware solution for Dank’s CNC motion control system called grbl. 

Compatible with the Uno and other 328p versions of the Arduino development platform. Version 5 is now compatible with running TinyG on the Arduino Due.

• Three stepper motors supporting X, Y and Z axes
• 8x microstepping
• 2.5 amps per winding (bipolar steppers) with proper cooling
• 12v-30v motor voltage supported
• Independent current control per axis
• terminal block connections for motors
• Uses TI DRV8818 stepper drivers

The schematic is available here.
