About this 3D model

this is a pololu stepper board for the reprap, it has on it all the power and end stop inputs and outputs. this has the ability to set the micro stepping on it, with jumpers. i have updated it a little since i posted the pictures, there is now a pull down resister and it is run a little better. i also posted it up on my blog too. http://mike-mack.blogspot.com/2010/07/another-board-it-was-slow-day.html
