    It looks like the driver is one of the many TB6560 based drivers

    some CNC kits sold comprise of motors & drivers and a 36V power supply
    the TB6560 IC has a maximum supply limit of 24V !!!! so the drivers don't last very long

    most if not all TB6560 drivers do have design problems

    with the 24V supply they should be OK but the low supply voltage limits the speed you can step the motor

    do you have a multimeter to do some simple continuity checks ?

    the main thing is to connect one motor coil across the +A & -A terminals
    and the other across the +B & -B terminals

    you can sort out the motors direction later in software

    PS
    your driver looks like another version of the TX14207

    going by this diagram it looks like the + step , + direction & + enable terminals are commoned and only have one + 5V connection to the breakout board +5V
