A schematic node is a point in an electronic schematic diagram where two or more electronic components or connections intersect. It is represented as a dot or a junction point in the schematic.

Schematic diagrams are graphical representations of electronic circuits that use standardized symbols to depict the components and connections in the circuit. The schematic node is used to show that two or more connections or components are electrically connected, without indicating the exact physical layout or routing of the connections.

The schematic node is an important feature of schematic diagrams, as it allows engineers and designers to create complex electronic circuits with multiple connections and components in a compact and easy-to-read format. The node also helps to identify potential points of failure or signal interference in the circuit, allowing for easier troubleshooting and optimization.

In summary, a schematic node is a point of electrical connection between two or more components or connections in an electronic schematic diagram.
