Online Circuit Diagram Drawing Software

A circuit diagram is a diagram that uses standardized symbols from physical electricity to represent circuit connections. ProcessOn supports online drawing of circuit diagrams, eliminating the need for tedious operations. Drag-and-drop operations are simple and efficient. It provides a full range of circuit diagram graphic symbols, as well as a large number of high-quality templates for cloning. Even novices can easily draw professional circuit diagrams.

Circuit diagram elements

Component Symbol

Represents the various components in the circuit, such as power supplies, resistors, switches, etc. Component symbols are intuitive and clear, allowing people to quickly identify and understand the various components in the circuit.

Connection

Indicates the connection relationship between components. It can be a straight line, curve or arrow line, which is used to connect the terminals or pins of different components.

Node

Indicates the intersection or connection point of the connecting lines, used to represent different circuit branches or cross-connection relationships.

Notes

Add annotations and comments to the circuit diagram to explain the circuit's functions, parameters, characteristics or other important information. This information helps to understand the meaning and purpose of the circuit diagram.

How to draw a circuit diagram

How to draw a circuit diagram Step1 How to draw a circuit diagram Step2 How to draw a circuit diagram Step3 How to draw a circuit diagram Step4 How to draw a circuit diagram Step5
1
Create a new circuit diagram, or create a new flowchart first, then add the 'circuit diagram' graphic symbol to the drawing area, or directly clone the publicly released circuit diagram template
2
Drag circuit components into the canvas according to the circuit operation order and rules
3
Use the transmission path symbols and wires to connect the components according to the operation flow of the circuit diagram
4
Layout optimization, through the 'match size' and 'align distribution' functions to make components of the same size and neatly arranged
5
Check whether the circuit diagram is correct according to the circuit operation process. You can publish it to the ProcessOn template community, or share it with your colleagues and friends.

Circuit Diagram FAQ

How to add circuit diagram graphic symbols?
Click 'More Graphics' in the graphics area on the left, check 'Circuit Diagram', and click 'Confirm' to display the circuit diagram graphic symbols in the graphics area.
How to create a connection?
Select the circuit diagram, move the mouse to the border of the diagram, and when the '+' appears, you can create a connection.
How to set the graphics distribution alignment?
Select two or more graphics at the same time and use the top toolbar to modify the arrangement, distribution alignment, size matching and combination relationship.
How to restore the historical version?
ProcessOn automatically saves history records to the cloud. Click 'File' and 'History' in the upper left corner, select the version you want to restore, and confirm the restore.
How to share collaborative circuit diagrams?
Click the 'Share and Collaborate' button in the upper right corner, enter the other party's account number to invite others to collaborate, or directly enable public sharing and share the link for others to view.

Why choose ProcessOn

ProcessOn Tools
Supports multiple graphics drawing, no need to switch between multiple software
Real-time collaboration, what you see is what you get, unified format, barrier-free collaboration
Historical files are automatically saved and can be restored to the required version at any time
Traditional drawing tools
The drawing ability is single, and multiple software needs to be purchased
Inconsistent formats, low collaboration efficiency, files being passed around, and poor timeliness
File version management is difficult, and historical versions are hard to retrieve
