JumboCAD EDA

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.
