From CNC.xyz Wiki
A Breakout Board is a device for connecting between differing interfaces. The most common type for CNC machines converts from a parallel connection to screw terminals for universal hook up. More advanced breakout boards incorporate signal filtering and protection, inputs for Limit Switches, Homing Switches and E-Stop, and output relays.
Some Motion Controllers incorporate a breakout board into their design for direct connections, and some all in one Motor Drivers handle everything from the input to the Stepper Motor output.
