Re: Reference Designator vs ${REFERENCE}
|
To add to what John says, if you investigate the attributes of each one, one will be on the silk screen layer, and the other will be on the assembly layer. You should be able to turn the appropriate layer off in the display if these are cluttering the up the display while you are working. I normally turn off the assembly layers and keep the silk screen layers displaying as I lay out a board, as that gives me the visual of how the physical board will look. Then once that is all happy I will turn on the assembly layers and adjust the designators as necessary to get a clear assembly document.
One, including the value, is to co-relate to
the schematic, and might not obviously or unambiguously relate
to the location. The other, the plain 'R14' located within the
outline, is to show for certain which part goes there during
assembly (population).

Hi,
I'm somewhat new to Kicad and PCB design for that matter.? When
placing footprints on the PCB it seems that the Footprint
Properties by default have both a "Reference Designator" and an
unamed property who's value is ${RFERENCE} [screen shot attached]
which seem to equate to the same thing on the resulting PCB
[screen shot attached].? Are both of these needed?? I know I can
turn off the "show" property for one of them -- but I'm wondering
how they different, if both are actually needed, and if not is
there a "bulk" update I can do to hide either one of them across
all the footprints without having to click into each footprint??
??
Thank you,
