TinyCAD free Circuit Design




TinyCAD - the free circuit design program


TinyCAD is a an open source program for drawing circuit diagrams which runs under Windows.
Warning: Do not pay for TinyCAD, it is free and always will be. There are no licensed sellers of TinyCAD.

Creating libraries of circuit symbols in TinyCAD is easy, but time-consuming. If you have some symbols you feel might benefit other TinyCAD users, then why not upload the symbols to this site to allow other users to download them?

30/03/2020 Version 3.00.02 of TinyCAD released


A new version of TinyCAD is now out. Head over to the Downloads page to get it. You can read the release notes here.

08/02/2020 Version 3.00.01 of TinyCAD released


After releasing a new version at the end of last year, there were a few minor problems that I missed in that release:

  • Embedded JPEGs were not being displayed
  • Netlist generation was broken for Protel and TinyCAD format files
  • There are problems with installing the Visual Studio Redistributable

This version attempts to address those issues.

Please report any issues on Github.
