When to Use Circuit Board Designer
Electronics Prototyping
Quickly design and visualize circuit layouts before building physical prototypes. Test component placement and connections digitally.
Educational Projects
Perfect for students learning electronics. Create clear circuit diagrams for homework, presentations, and lab reports.
Documentation
Create professional circuit diagrams for technical documentation, manuals, and project proposals with export to PNG.
Rapid Iteration
Test multiple circuit configurations quickly without physical components. Save and compare different design versions.
Team Collaboration
Share circuit designs with team members via JSON export. Review and modify designs collaboratively before manufacturing.
Troubleshooting
Diagram existing circuits to identify issues, plan modifications, or reverse-engineer circuit board layouts for repairs.
Frequently Asked Questions
What is Circuit Board Designer?
Circuit Board Designer is a free online tool for creating PCB layouts and circuit schematics. It provides a visual canvas with drag-and-drop components, connection tools, and export functionality for electronics prototyping and design documentation.
How do I use the Circuit Board Designer?
Select components from the library panel on the left, drag them onto the canvas, and position them using the grid. Switch to wire mode to draw connections between components. Use the export buttons to save your design as JSON (for later editing) or PNG (for documentation).
Is this circuit board design tool free?
Yes, Circuit Board Designer is completely free to use with no registration required. All features including the full component library, connection tools, grid alignment, and export functionality are available at no cost.
What components are available in the library?
The component library includes resistors, capacitors, LEDs, transistors, integrated circuits (ICs), power sources, switches, diodes, and connectors. Each component can be placed, moved, rotated, and connected on the design canvas with proper labeling.
Can I export my circuit board design?
Yes, you can export your design in two formats: JSON format preserves all component positions, connections, and properties for saving and loading designs later. PNG format creates a visual image perfect for documentation, presentations, and sharing.
Does the tool work offline?
The Circuit Board Designer runs entirely in your browser using HTML5 canvas and JavaScript. Once the page is loaded, the core functionality works offline. However, exporting files requires browser APIs and an active session.
Is my circuit design data secure?
Yes, all circuit designs are created and stored locally in your browser. No data is sent to our servers. Your designs remain private and secure on your device unless you choose to export and share them.
Can I import existing circuit designs?
Currently, you can create new designs from scratch using the component library. Future updates will include JSON import functionality to load previously exported designs for further editing and modification.
