    Ok well don't know this BOB but I'll take educated guess and say that VCC is the positive to power the board and GND is obviosly the ground.
    The +5v & Gnd will be a output the BOB provides for powering other things.

    Regards the wiring then Yes the diagram is correct and will work. Don't take power from the Vdd to the Pul/dir.

    Can't see the Linux link but again I'll take a guess.? . . . Chances are he's done this so when there a Limit or E-stop it disables the drives but doesn't Kill power so the Motors stay Energised and don't lose holding torque, the Enable just stops any signals getting thru.
