TinyCAD is an open source schematic capture program for all versions of Microsoft Windows. We use TinyCAD to produce circuit diagrams because it is easy to learn and use, and because it is free, the diagrams we create are easily edited by others to customize for their needs.

TinyCAD can also be used to create printed circuit boards, and can export “net list” information to applications such as FreePCB, which we recommend for creating printed circuit boards.
