If it's a little RA130 motor then remember the SN754410 will drop 1.4V anyway. So a 4.5V supply will only supply 3.1V to the motors.
Q1>Which one is easier to control a dc motor speed + direction: sn754410 or L298?
I live in united arab emirates, I don't have access to any of these parts l298 or sn754410
Q2> Which store in US or UK do u recommend i should buy, because i made 2 POBOX one in UK and US to buy these kind of parts l298 or sn754410?

Thanks 3v0 for the file, I found it but the problem is i can't copy it from your schematic till mine. I think i need to save it as lbr first i am looking over the net on how to make lbr file but if anyone know how to make lbr file or how to copy from one schematic till another i appericate your help.
The datasheet from Texas Instruments is confusing.Thanks it work. My other question about does sn754410 need diode for a bipolar stepper motor of 7.5degree/pulse, 5V and 800mA.
or its build in diode,
