CYD Pendant RJ12 Adapter

This is an RJ12 interface for a CYD display based CNC pendant. It simplifies the wiring and also adds some protection. You can read about the project on my wiki. 

This is design for use with FluidNC Firmware. The RJ12 interface is a standard display and pendant interface for FluidNC.

You will need a 2.8" CYD (Cheap Yellow Display) and an encoder to complete this project.
