Thanks again, John. It was suggested by others that I pull the TO-3 footprint from another project, like those on the N8VEM-S100 web site. I’ll look into that, especially the link you provided below. I want to do exactly what I have seen you do, that is include the Pololu regulator stacked on top of a TO-3 regulator. Further, I found another 5V switching regulator from EZSBC called the PSU5, and LM323K replacement. (http://www.ezsbc.com/index.php/featured-products-list-home-page/psu5.html#.VgK07Jce3s5). This gives me three regulator options: Standard LM323K, EZSBC PSU5 (fits in the TO-3 space, but without a heatsink) and the Pololu part. I am looking for the TO-3 footprint only because I don’t have good mechanicals on the TO-3 part in order to make my own. BTW, the link to the S-100 appears to only have 62 pins, and they are on 0.1” centers, not 0.125”.

These days I overlay a TO-3 on top of a Pololu regulator. No extra space, more options. I sent you a link yesterday for the S100 connector. John From: n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] On Behalf Of Bob Bell Good morning group, I have been searching now for ½ hour and cannot find a footprint in the KiCAD v4 library for a TO-3 case semiconductor (typical LM323K). Is it actually there, and I keep missing it? If so, please point it out to me. If it isn’t there, do you have a footprint for TO-3 that you would be willing to share? Also, a few days ago I posted a message in regards to an S-100 edge fingers footprint (not the edge connector, but the component that creates the edge fingers on the board). I got one response, but it didn’t work. Is there anyone else with a confirmed functional S-100 edge fingers footprint they would be willing to share? Thanks for your help! Bob Bell -- -- |
