That's correct.   The OCXO is a brand new part that is thrown in and has
nothing to do with the board the Rb is on.  Same for the DE-9 connector.  I
can use the connector but the OCXO is not useful to me at all.   I did wire
it up though and my counter verified what the sticker says.   3.3 volts in
according to the data sheet in the auction listing, however the data sheet
is for a different part.  Close enough, I guess.
