Thanks everyone!
My solution is to get a shrowded or housed panel connector and use a female
to male adapter to mate to the programmer/debugger.

</div>I think we're all a bit unclear what you want - maybe you could d=
raw an example picture and attach it?<br>
<br>
As Bdale mentioned, a right-angle header strip that is exposed through a ho=
le in your project's casing is a possibility; indeed I could swear I=
9;ve seen right-angle header strips with pins so long that, if mounted clos=
e to the edge of the board, would stick out of the case far enough to fit a=
connector onto the ends without it touching the case (assuming the pins st=
ick out through little individual holes .<br>
<br>
That said, I don't think you'll really want the pins to stick out l=
ike that in the long run. =A0Not only are they at risk of being damaged or =
broken off from bumping into something (say, when you move your project, or=
put it away when it isn't in use), and those pins could in turn damage=
something else, including your hands. =A0I'm sure we've all had th=
e experience of finding some random through-hole component or row of pins t=
he hard way.<br>
<br>
It sounds like you want to be able to reach these pins easily e.g. for hack=
ing purposes, so I would suggest one of three options (roughly in order of =
preference):<br>
<br>
1. Use a shrouded male right angle header, and mount it so that the ends of=
the pins sit just under the surface of your project's casing. =A0If yo=
u choose a common size, it's easy to find pre-made cables with appropri=
ate matching connectors (you may already have such in your junk box). =A0Ju=
st chop off one end of said cable and hook the wires to whatever.<br>
<br>
2. Work a 0.156" male card edge into your board layout, designed so th=
at you can plug a female edge connector into/onto it. =A0Card edge connecto=
rs of that pitch are big and easy to handle, especially if you have large h=
ands or poor coordination (like me), and it's quite easy to solder wire=
s onto the terminating pins.<br>
<br>
3. Do the same thing, but using a 0.1" pitch connector. =A0These are l=
ess common, for some reason, and are a little less easy to handle due to th=
eir smaller size, but they're otherwise as flexible as the 0.156" =
size.<br>
<br>
4. Use a right-angle female header. No need for a mating connector here ini=
tially - you can just jam wires or individual male pins into it as needed.<=
br>
<br>
Any of these, if placed correctly, would also allow your project to accept =
a peripheral mounted directly against it, sidecar style, if it should come =
to that.<br>
