ARM made a new "standard" for cortex debug, because smaller is cooler y0. Read their description of it here
The takeaway is, 2x5, in a svelte 1.27mm pitch
The common older style is 2x10, but in fatduino 2.54mm pitch.
Helping clutter your desk and let you use two of your existing cables, for ultimate bigmessowires style.
Olimex 2.54mm->1.27mm adapter (Also available as Digikey part number: 1188-1016-ND)
Like above, but with "moah fr33d0M" and now supporting windows! 20pin<->10pin with power options -> pic1 -> pic2
not super cheap, (he gets from samtec directly) but it has partial shrouding, only around the pins where the key on the cable goes, so it takes up a lot less space. [Digikey partnumber SAM8799-ND](Or just http://www.digikey.com/product-search/en?keywords=SAM8799-ND)
< aandrew> I use the standard everyday fucking used everywhere digikey 1175-1629-nd
Much much much cheaper, but fully fully shrouded, so more board space.
Note, this is actually more expensive than the shrouded version above.
Right angle, shrouded. For that low profile look.
Some people occasionally espouse the virtues of tag-connect. They are wrong.

it looks great on paper and if you don't need retention clips (i.e. you aren't oing to be debugging with it or flashing 2GB flash via JTAG) it's actually not half bad for press down, flash, done but the second you need it to stay there you are drilling four gigantic fucking holes which completely eliminates the size advantage of it your other option is two smaller holes and a little clip that goes on the bottom, but that only works for about 10 hours or so before the metal starts bending and it no longer holds, so you resort to wrapping the thing to the board with 30AWG like a spider wraps a fly. which works until you need to take it off
it's just fail
you want to do debugging? gotta drill those fucking HUGE holes for retention or use the clip on the bottom which works its way loose you want tiny footprint? use a fucking bed of nails and 4 test points. way smaller want to be frou-frou and have spring contacts on the cheap? Use something like isptouch for way cheaper
(much later, someone though this was arrogant legacy thinking.... and then...)
21:12:28 @englishman | aandrew: the tag-connect arrived and everyone hates it including me
21:12:31 @englishman | what a stupid device
21:15:30 jadew` | englishman, what's wrong with it?
21:15:40 @englishman | it's a solution looking for a problem
21:16:06 Steffanx | Werent you all into tagconnect?
21:16:15 @englishman | yeah then i actually tried it
21:16:28 @englishman | troll fail
