Hello,
I recently bought: http://www.miniinthebox.com/nl/l298n-stepper-motor-driver-controller-board-module-voor-arduino-werkt-met-de-officiele-arduino-boards_p903378.html
But i've got a question. Can i supply the power for this module using the Raspberry pi?
If not would a 9v battery work is that possible since it is a 5v module?
Isn't 9v to much then?
Power the whole board - definite NO.
Power the logic side only - maybe, I wouldn't risk it myself. (I'd use opto-isolated motor driver
with something expensive like the Pi, rather than risk blowing it up)
BTW what motor are you proposing to drive with that?
You may find some useful info in Stepper Motor Basics

Just 2 motors.
One for steering and one for going forward/backward. And they just have 2 wires? + and -
So i can't connect a 9v battery to the motor shield :(?
or from the raspberry?
If you mean a PP3 type of 9v battery then that is completely unsuitable - it cannot provide nearly enough current.
As a general comment you must have a power supply that matches the voltage required by the device it is connected to.
