JumboCAD EDA V3.1 contains 3 packages, Schematic Capture, PCB designer and Library Editor. They are 100% free to use but I reserve the right changing  the future release to paid version.

I am an individual software developer, I write JumboCAD EDA as hobby this moment, so little support and no warranty

Schematic Capture

  • Easy to use, place parts, move parts, place wires only simply by moving and dragging your mouse. Use mouse wheel to zoom in and zoom out.
  • Simple hot-keys. CTRL-C (copy), CTRL-Z (Undo), delete (delete), F1 (Toggle pan mode), CTRL-W (draw wire), CTRL-R (rotate). No other hot-key
  • Support PAN mode.  Use "F1" or mouse wheel to zoom in  and zoom out.
  • Use XYCE as circuit simulator engine.
  • BOM generation, PCB netlist generation
  • Auto annotate.




PCB designer
