Make a Reprap Robot Part 1: The Electronics – Weekend Project PDFcast

Getting the electronics set up is the first step to getting a working reprap robot together. Besides 3 stepper boards, 1 dc motor controller board, a PWM board, you’ll want two arduinos and an arduino tx/rx thingy!

Download the pdf for more information and then download the test code so that you can hook up the boards to stepper motors and dc motors to test them out.
