Have you seen Digi-Key’s new FREE online schematic and diagramming tool? It’s called Scheme-it and can be used in most browsers with no plugins required.
This great little freebie tool has a library of electronic symbols, as well as an integrated Digi-Key component catalog. Better yet, there is a built-in BOM manager to keep track of all your parts. Scheme-it is an incredibly easy-to-use tool—only six pages to the Help Doc. Very cool!
Only registered Digi-Key users can save and share their Scheme-it designs. However, registration is painlessly simple. All you’ll need to do is visit www.digikey.com, sign up, and just draw it!
