PCB schematic Note large summary of issues

1. Wire () between the components with wire () command instead of the line (/) command, although on the surface, both are straight lines, but the color slightly different, but the wires () command to place the electrical characteristics, and the line (/) command placed on the lines are not electrical significance, There is a fundamental difference between the two.
2. Note the difference between the explanatory text (Annotation) and the network label (NET label): The description of the text is not electrical characteristics, but purely textual interpretation, and the network marking is electrical characteristics, it can be the circuit diagram with the same network designator electrical connection is connected, That is, in more than two interconnected networks, the electrical connection points that should be connected together are defined as the same network designator, so that they belong to the true same network in the electrical sense.
