need an experienced eye to cast a look over this driver

what actually comes out of a break out board to in turn make the motor driver do what it does

Just a 5 volt signal,the direction signal is either high or low which determines which way the motor turns and the step signal is a pulse (square wave).
If I get time this weekend I will connect one of the drives I have to a motor and have play then let you know how I get on.
