JumboCAD EDA 4.0
JumboCAD EDA V4.0 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), CTRL-M (Move), CTRL-F (Find), 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. (this features was disable this moment)
- BOM generation, PCB netlist generation
- Auto annotate.
