The other thread has a comments thread of its own too you know
Are you kidding? A whole extra click?
The reason I've soldered ribbon straight to it is to keep those screw blocks free for potential future connection, and so I dont have to screw/unscrew wires.
Figured it was something like that, though I was trying to decide if it was a good way to go, i.e. you're still stuck with signals in parallel then. But it's not exactly terrible, either.
Seen the JBperf breakout board? I just got one and it's great (though I used header connectors instead of screw blocks since all I ever do is hang an oscilloscope off it, so why put in a wire just to use it as a pin?
Oh, and, you can make 0.200" pitch headers out of 0.100" if you dremel a slit in the tip of a pair of needle nose and then push out every other pin.
Just having pins or plug or socket out the bottom would have been enough for both testing and for use in a car. However, the cost of the FM connector is the same as just one or the other, and it allows another small board (or large) to be hung off the top of the MCU board.
Oh, I like that you can use a standard cable, ALWAYS a good thing. And of course, you don't have to use half the pins for grounds like a certain automotive DIY ecu just because the connector they are borrowing often does it that way. It's bad enough the few outputs on the CPU don't make it to the PCB, and it's worse the signals that make it there can't make it out of the box, especially when there are 18 redundant pins.
Good idea!
You probably can get them, but not locally here, and they don't come with one. I have just had an idea though, and if it works I'll post a pic of it here when I'm done.
Just to give you some ideas....
It's not important if you install once and leave it there, but if you are pulling it out and pushing it in often, then it becomes important. I nearly stuffed my MS2 card in the same way. I was thinking the same thing with these, but the dual row IDC style are a lot easier to get straight than the MS2 card is.
Ha! That's what you think!
The reason they tend to use the shrouds is not for alignment so much, all that takes is a bit of care on assembly. They do it for shock and vibration resistance, the two plastic bits end up being fixed to the board directly so there's less shear force on the pins. So they say.
