gEDA Symbols and footprints
- un-tested gEDA symbols and footprints
- All of these Symbols are heavy symbols. gEDA has already provided most of the above symbols in light format for us to modify. The above symbols include more information than normal to save some time instead of configuring each symbol every time you use them.
Other footprint libraries
"Open Symbol Project" with Mark Whitis "The Open Symbol Project aims to create an open collection of schematic symbols and PCB footprints released under a license that does not interfere with use in either commercial or free projects. ... can easily be modified to accommodate various design rules."
What can we do to help the Open Symbol Project?
PCB123 Libraries includes some footprint libraries (and a gallery of PCBs).
See also the SFE Footprint Library Eagle.
A collection of footprints for use with the gEDA/PCB program. Also on the site are a variety of scripts to build footprints and automate PCB layout tasks.
I'm a little intimidated by these little QFN packages. Alas, I've been asked to use a chip that doesn't have any alternative package.
Any other tips?
