Hi, I'm working on a project where i need to control 6 bipolar 4-wire stepper motors (5V) using either one or two boards. help needed as i have no idea what im doing or looking at. all help is highly appreciated.
You need one motor driver board per motor. One Arduino can control several motor driver boards.

Stepper motors are current driven, not voltage driven. Tell us exactly which motors you mean.
Hi,
What s the application?
Thanks.. Tom... 
Adafruit Motor Shield V2 can control 2 steppers. Board is addressable so stack 3 of them.

But it does not have current limiting (to protect the stepper motor when using a high voltage power supply) or micro-stepping for smoother operation.

or micro-stepping for smoother operation.
Even though that shield is not a good choice for driving steppers it does support micro-stepping.

Thanks for the correction.
