I noticed on some schematics there is an arrow (similar to the "IN"/"OUT" symbol) with an "L" in it, and there are some that are a circle with either the word "PIN" in it or the circle has an "X" in it. I'm not sure what that means. Anyone have any insight?
Thanks.
Could you provide a an example of such a schematic? Context is everything.
These are pins used for I/O connections used on the PCBs. In, Out, LED, ground, etc.
Here are a couple of examples. The Hipster shows the L and PIN symbols, the Fritter shows VB, VC, and X'ed out circles.
That is the pad for wiring the anode cathode of the LED to the footswitch.
The arrow is a label for the net name. In Eagle, click on "Name" for an net and choose the option "place label". In a second step, click on the label and choose "info". Click the XREF option.
just to add to that. The "arrow" symbol is the net and used to connect stuff without the use of a line that would need to cross over the schematic to make things cleaner and easier to read. With the L, IN and so forth, Brian uses it basically as a label, but not so much for electronic functionality.
The pin circle is related to the pin that is actually put on the pcb, as the symbol and part are directly connected to each other in Eagle.
hope that makes sense
Thanks for the replys. I had to look up Eagle. It makes more sense to me know that I see the program.
