Fritzing's CAD Neatly Documents Circuit Designs
Documentation is a critical component of any technical product, whether it's hardware or software. Yet too often we give it short shrift, even though there's some free resources available to help you out. Besides helping users out, documentation is a key to securing patents, collaborating with partners and even just remembering where you left off with that project from a month ago. If you want to support an electronic or micro-controller circuit, with graphics and parts added to your materials, the Fritzing electronics CAD package is worth trying. Specifically tailored for laying out and documenting your electronics projects, it has a library of parts that includes resistors, transistors, caps, wires and micro-controllers. Various flavors of each are represented. The detail is high enough that it actually shows the color codes on the resistors. The program uses vector graphics with anchor points, so you can run wires between your devices to represent actual circuits.
