Hello,
After posting a few days ago about one of my '5680A's having the voltage
converter installed - but not connected - I've done a bit of
reverse-engineering and sleuthing around and (probably) have a fairly
complete picture of what it would take to populate that section of the
board. That information may be found here:
http://ka7oei.com/10_MHz_Rubidium_FE-5680A.html
This page is a work in progress, using my LPRO-101 page as a template
and unashamedly stealing a good chunk of its content - most of which is
directly applicable, anyway!
Note that I haven't done the board population myself and there *may* be
additional jumpers that need to be added/removed - or, as I suggest, one
could avoid that problem and simply connect to known V+ and +5 volt
points instead.
If you happen to have one of those boards with the installed (but not
connected) regulator, information is also included on which two jumpers
I needed to add to enable it: Again, YMMV, DNTHFB, etc...
If anyone populates their own board, please let me know how it worked out.
I add this mostly out of interest expressed by a few others that emailed
me. It's no doubt far easier/cheaper to simply add an outboard 7805 (or
switching converter) than populate the board, but hey, why not?
73,
