From the project
Hardware design for modular CNC controller
This module provides 4 axis of step/dir/enable signals. Step/dir signals are differential 5V. Enable signal is at the same voltage as controller's DC input.
The connectors are RJ45 (intended use is either with motor-drive specific breakout board or a generic screw-terminal type breakout board).
RJ45 green LED is wired to enable signal.
