IMHO trying to make 5V from 15V with an onboard linear
regulator is a loser. The power dissipation is going to
be so high you are just installing a space heater for
your VCOs.
I think that the .156" connector should be supported, and the
.1" connector added ~if and only if~ board density permits.
You could easily make up an adapter harness for ANY of the above...
10V of drop on the regulator (guaranteed :^) is too much (imho)
