01 / Schematic

Circuit diagram software, in your browser

Start with a blank sheet or an example circuit. Place components from the library, wire their terminals and edit values with engineering units. Your schematic stays connected to simulation and PCB layout.

What you can do

Search the component library, rotate parts and connect terminal to terminal.
Use named nets, connectors and test points to make larger circuits easier to read.
Undo edits, align selections, collapse sidebars and use focus mode for a larger drawing area.
Export circuit JSON for a local copy, or sign in to save projects online.

The OhmNest schematic editor with an RC low-pass filter.

02 / Simulation

Simulate and measure

Simulate circuits online with transient, DC and AC analysis. Explore waveforms using an oscilloscope, function generator, multimeter and Bode plot.

03 / PCB layout

Lay out a PCB

Move from an electronic schematic to PCB layout in OhmNest. Place footprints, route tracks, inspect design rules and export manufacturing files.

04 / Electrical

Document the design

Create electrical drawings and documentation in OhmNest. Organize sheets, devices, terminals and wires, then produce project reports and drawing exports.
