gShield v5


We are now selling the new v5 version of the gShield, formerly grblShield. Other than the price, there is very little difference between the v4 and the v5. Both can be used on the Arduino Uno to run grbl, or on the Arduino Due to run the TinyG Due port. The v5 power jumper simply allows the gShield to be run as a native 3.3v device from the Due, instead of a 5v device. There are no other functional differences.


Should I use a gShield?

The Arduino gShield is a complete hardware solution for Dank's CNC motion control system called grbl.  The gShield is also used in the Inventables "X-Carve" CNC machine.  The gShield is also a good choice for any Shapeoko based machine.  

Compatible with the Uno and Duemilanove versions of the Arduino development platform.
