A Circuit Diagram Maker

Circuit Diagram enables you to make electronic circuit diagrams and allows them to be exported as images. Ideal for use in coursework, you no longer have to use image editing programs to paste components together.

Circuit Diagram 2.0 Preview

A preview of Circuit Diagram 2.0 is now available for download - Circuit Diagram 2.0 Beta 1 - please test it out.
You can download more components at http://www.circuit-diagram.org/components and learn how to create your own at http://www.circuit-diagram.org/wiki/Creating_components.

Official Website

The official website for Circuit Diagram can now be found at http://www.circuit-diagram.org/ - please visit for requesting new features and components in future releases, help and documentation on designing circuits, and more.
If you would like to link to us, please link to www.circuit-diagram.org rather than this page - thanks!
