<konsgn[no-Mic]> Out of curiosity, what was the logic behind facing the keyd ports inward on the glasgow? The key's become symmetrical for a 2 port hat as rwhitby is designing that way.
<d1b2>
<rwhitby> @xabean yes, DUT may be clearer than Target
<d1b2>
<rwhitby> But I'm wondering if DUT requires prior knowledge, whereas Target is a term that anyone will know (even if they have not heard DUT before)
<d1b2>
<xabean> ah yeah, know your audience.
<d1b2>
<Attie> @konsgn[no-Mic] as one row is nearly all GND, and the other is the signals, I imagine that "signals inside" was chosen for ease-of-routing...
<d1b2>
<Attie> then, to maintain pinout/compatibility between ports, it needs to be the same, with the samy keying, and thus the pinout needs to be rotated 180'

sits on Attie.
<d1b2>
<Attie> sad face

<konsgn[no-Mic]> Merp, I don't follow that. I can see how the traces inwards could have a little easier time routing, but it's pretty easy getting one, and you can sometimes even 2 squeezed traces between the pins of a 2.54" header pins.... I just thought. hey, do keyed pin headers that are pcb mount even exist.....? if not, then this is a moot point as keys are only useful for cables ribbon or otherwise.
<d1b2>
<rwhitby> certainly the keyed headers are good for the normal use case of cables for glasgow
<d1b2>
<rwhitby> addon boards is a rare use case
<d1b2>
<konsgn[no-Mic]> what I was thinking was have both keys point to one side, bottom or top, that way you could have a pcb that sits on top and can only go in one way... but I don't think keyed pcb headers actually exist so that would explain that....
<d1b2>
<Attie> Q&A is a bit potato-esque, and the front was chopped off unfortunately
<sorear>
ooo
<d1b2>
<Attie> heh, an awkward ending too 🤪

would Mouser PN 571-1023874 mate with the shrouded IO connectors on Glasgow?
<whitequark[m]>
I think it will but I'd appreciate if someone else also checked
<gruetzkopf>
it looks like it will - the latching mechanism for the cable terminations is exactly opposite of the "common" ones in the readymade jumper though
<d1b2>
<Attie> yeah - looks good to me

<gruetzkopf>
according to the catalogue the matching contact is Mouser PN 571-6-87756-6
<whitequark[m]>
thanks everyone!
<gruetzkopf>
the common jumpers use a plastic "spring", these use a metal tab on the contact

whitequark[m]: 571-1023874 is from the AMPMODU MOD IV series. this is a bit of a strange and probably usually obsolte, but still manufactured series
<electronic_eel>
one of the usecases the author mentions there is exactly what you want: plugging a connector with single crimped wires into an idc socket
<electronic_eel>
but you will most probably need the correct contacts for this connector (what gruetzkopf posted), the contacts for regular "DuPont" style sockets won't fit

<gruetzkopf>
(i even dug out my imperial pcb ruler from the local high-temp pcb supplier to check)
<electronic_eel>
gruetzkopf: check what?
<gruetzkopf>
connector fit in these specific idc sockets
<electronic_eel>
the pn of the correct contacts?
<electronic_eel>
ah, got it.
<gruetzkopf>
(was a bit annoying to do because was actually using that glasgow at that point
<electronic_eel>
hehe, always have a spare glasgow lying around ;)
<gruetzkopf>
my revB is at home and the next two are in the big queue ;)
<electronic_eel>
ok, then esden will have you covered soon (*)
