I received a Motor/Stepper/Servo shield in one of the kits I purchased a very long time ago ( Picture provided ) I know that this was designed for the Arduino, but wondering if this could be setup with the raspberry pi, and if so, how? If anyone can provide some information on what would be needed that would be awesome. I am trying to hook up four dc motors to run four wheels for a remote car, and it would be easy for me to use this shield.

Re: setting up Motor/Stepper/Servo Shield on Raspberry PI
Wow.. we don't see photos of legitimate v1 Motor Shields very often. ;-)
I'm afraid there's no easy way to make that one work with a RasPi though. With a v1 Motor Shield, the Arduino has to generate all the PWM signals that control the motors, then shift those signals to a 74AHC595 which controls the H-bridges. The RasPi isn't very good at generating PWM in software because of timing limits in the operating system.
