Tools/Free schematic maker

Free schematic maker.

Make a schematic diagram by describing the supply, components, values and connections. The schematic maker draws the circuit logic with standard symbols, so you can trace the signal or power path before you build.

The drawing

What a schematic diagram is.

A schematic diagram shows the electrical relationships between parts, not their physical positions on a board. Symbols represent components and lines represent the nets that connect them, so the circuit can be read from input or supply to return.

It is the drawing used to design, analyse and troubleshoot a circuit. Include each component's value and the connections that matter, then refine the drawing as the circuit changes.

FAQ

Common questions

What is a schematic diagram?

A schematic diagram is a standardized drawing of an electrical or electronic circuit. It uses abstract symbols to show the components and their logical connections, rather than the physical position of the parts.

How does the schematic maker work?

Describe the circuit's purpose, supply, components, values and connections in plain language. The schematic maker turns that description into a structured circuit drawing that you can refine with follow-up requests.

What symbols are used in schematic diagrams?

Common symbols include resistors, capacitors, inductors, diodes, transistors, integrated circuits, switches and ground. Their standardized forms let engineers and technicians read the same circuit drawing.

What is the difference between a schematic and a wiring diagram?

A schematic shows electrical function and logical connections with symbols. A wiring diagram shows the physical layout and routing of wires, which is useful for installation and repair.

Can I export a schematic diagram?

Yes. Export the finished diagram as SVG, PNG or PDF for documentation, reports and presentations.
