Scheme-it is an online schematic and diagramming tool that allows anyone to design and share electronic circuit diagrams. The tool includes a comprehensive electronic symbol library and an integrated Digi-Key component catalog that allows for a wide range of circuit designs. Additionally, a built-in bill of materials manager is provided to keep track of parts used in a design. Once a schematic drawing is complete, users can export it to an image file or share it via email with others. Scheme-it works natively in all major web browsers without requiring the use of any plugins. Only registered users are able to share and save designs.
