TinyCAD is a program for drawing electrical circuit diagrams commonly known as schematic drawings. It supports standard and custom symbol libraries. It supports PCB layout programs with several netlist formats and can also produce SPICE simulation netlists. It is also often used to draw one-line diagrams, block diagrams, and presentation drawings.


  • Flat or Hierarchical Schematic Entry
  • Many popular PCB Layout compatible netlist formats
  • Convenient support for embedding graphical images in drawings

User Reviews

  • I just don't believe how is it possible to have so much good reviews for this SW, it misses so much features to be just useable : - folio managment - folio wire following tool - .sgv import for external libraries - nomenclature managment There is no dynamic libraries : you modify a symbol in a middle of a project, you have to replace ALL the symbols one by one by hand in the whole project .... this is insane ! Trying to work with TinyCad is just a waste of time. Simple is not simplistic. You have try Qelectrotech just for comparison (also free, and open source, and linux/mac/Win, bla bla bla)

  • Using/testing TC for a few weeks now : - randomly corrupt custom libraries saves - inexusable basic functions is missing : - reorder sheet is not possible - reorder lists (other than alphabetical order) is not possible - no version managment, no index managment - no upgrading document content when object is modified in the librarie - no follow-up of the names of the cables/busses from one sheet to another Really painfull to have another usage but tiny project with tiny expectations with the output.

  • Amazing. This program has saved thousands of man-hours for myself and colleagues. At first, one would think it is only good for circuit-board design. Not the case at all. I am an audiovisual design engineer, and this is PERFECT for conceptual (pre-sales) design. AutoCAD is great, and everything will end up being in there, but it takes time. TinyCAD does not. Once you create a decent library, you can pump out drawings at a blistering pace. Bottom line, I would pay for this product if it weren't free. It is that damn good.

  • VirusTotal ( www.virustotal.com ) tells me that the latest rlease ( TinyCAD_2.80.08_631_Production_Release.exe ) contains viruses. The old release TinyCAD_2.80.03.514_Production_Setup.exe seems to be clean. This will prevent many people from wanting to upgrade.

  • Great job! Simple, fast, light tool for drawing schematics. It has snap to grid, drag connected component, 90degree (and more) wire guide, rotate. Drawing your own parts is simple and fast. I worked in Protel, trying KiCad, working in DraftSight (for laser cutting), SolidWorks and this one (TinyCad) is very nice, free and open. You should setup page/printer first, so program can take paper size from your printer driver. Then it will fit into page at 100%
