[hpsdr] Some thoughts on plug-in board layout

[Carl Morris, WN3DUG]

Steve, N7HPR,

I believe you said:

"So looking at the card from the component side, the DIN connector is on the bottom, connectors on the left.  So nothing should be in top or to the right?"

Wouldn't the connectors be on the right, according to Phil's (N8VB) "ATLAS PLUG-INS" drawing note in the Plan View? (Upper left hand corner)

By the way, Phil, N8VB; I like the concept you have shown in the "ATLAS PLUG-INS" drawing!

Phil and group,

Attached is a mechanical drawing I did to hopefully understand the dimensions of an individual card.  I placed 100mm, 120mm, 160mm, and 185mm dimensions.

Will someone tell me what the base measurement system will be (metric or inches)?  I think it should be metric, however, the DIN 41612 has base dimensions appear in inches.

Phil, in your ATLUS PLUG-INS drawing, you show 12.6 mm from the bottom of the PCB to the end of the DIN 41612 plug.  I think this is actually 7.37 mm.  The 12.6 mm is the top of the DIN plug plastic to bottom, not how it is mounted to the PCB.

The DIN plug that I used what the one Lyle called out for JANUS (AMP P/N 650473-5).

I don't really understand the "external connector area".  Is this PCB material?  Or is this just an placeholder?  What is the interface plane?

So looking at the card from the component side, the DIN connector is on the bottom, connectors on the left.  So nothing should be in top or to the right?  What notes should be added to this drawing to aid the prospective card designer?  Hopefully this drawing can be used as a basis for anyone starting a card.  Everyone, please comment on the dimensions you think should be put on it.

The other drawing I would like to do has common components that should be on all plug in boards (serial epprom, etc.).  I need help if someone could list what these items are.  I can look at JANUS and OZY for examples.
