Schematic Maker
Quick answer: Build electronic schematics online with a 480+ symbol library and circuit simulation for supported models. Useful for Arduino, Raspberry Pi, and circuit exploration.
Best fit
Use this browser workflow when an editable drawing, structured electrical data, fast sharing, and common exports matter more than a native specialist desktop format.
Not the best fit
Use specialist software when the project requires native DWG intelligence, enterprise plant engineering, advanced production PCB/DFM, arbitrary vendor simulation models, certified power studies, or mechanical panel engineering.
Available capabilities
- 480+ electrical and electronic symbols
- Supported-model DC, transient, and AC analysis
- Pin-to-pin routing and net labels
- PNG, SVG, PDF, DXF, netlist, and BOM outputs
Representative test
Open a relevant sample, change one component and connection, then verify the exact drawing, report, analysis, and export your job requires.
Other tools buyers evaluate
KiCad, EasyEDA, Fritzing, CircuitLab. Verify each vendor’s current primary documentation before purchase; this page does not claim feature parity.
Frequently asked questions
What is the difference between a schematic and a wiring diagram?
A schematic uses standardized symbols to show circuit function and connections. A wiring diagram shows the physical layout. CircuitDiagramMaker supports both styles with 480+ electrical and electronic symbols.
Can I simulate my schematics?
Yes. Supported component models can run DC operating point, transient analysis, and AC frequency sweep with waveform and Bode views. See the simulation compatibility page for exact limits.
Can I create Arduino schematics?
Yes. The Hobbyist symbol pack (123 symbols) includes Arduino boards, sensors, modules, resistors, capacitors, transistors, and standard electronic components.
Does it support standard schematic symbols?
The library includes 480+ electrical and electronic symbols across four packs. Symbol reference pages identify IEC, ANSI/IEEE, or other standards where specific standard data is available.
Can I export a Bill of Materials?
Yes. CircuitDiagramMaker auto-generates a Bill of Materials from all placed components, capturing part numbers, values, and notes. Copy to clipboard or export as CSV.
How does auto-routing work?
Our Manhattan wire routing automatically routes connections at right angles with pin-to-pin snapping. Wire jog handles let you manually adjust routes, and color-coded wire labels keep circuits readable.
Is there a schematic diagram app or free download?
There is no schematic diagram software to download — this schematic maker app runs entirely online in your browser, free to start, on any operating system. Nothing to install, no Java, no plugins.
Is this a free schematic diagram tool?
Yes. It is a free online schematic diagram tool on the starter plan, with paid upgrades for unlimited schematics, all 480+ electrical and electronic symbols, and supported-model DC, transient, and AC analysis.
Can I simulate schematics in this online schematic editor?
Yes — unlike most free schematic tools, this online schematic editor includes a SPICE simulator with DC, transient, and AC analysis plus a waveform viewer.
