CNC.xyz Arduino Compatible Grbl Shield for CNC Stepper

Grbl Breakout Board for Arduino UNO and others. Want to use Grbl and an Arduino with your CNC setup, but don't have a way to breakout the signals and connect to your machine? Look no further! Plugs directly into an Arduino UNO (or compatible Arduino platform). Arduino is NOT included. Will require the soldering of the headers along the edge for DIY assembly. Note: The pinout listed is for Grbl version 0.8 specifically. The layout changed for Grbl version 0.9, where the spindle control has been swapped with the Limit Switch for the Z-Axis.
