Permanent mounting of GPIO wiring

Sat Jun 04, 2016 3:10 pm

Ok, eventually we all get to that point where the breadboard testing of the GPIO communication through whatever peripherals we're using is tested, confirmed, and ready to go.
What do you guys do when it comes to permanently, physically installing the final product?
I've got my peripherals beautifully soldered up on a protoboard, and could -- I suppose -- just use the 40pin breakout T-cobbler that connects to the Pi's GPIO, but it's a bit of a clunky overkill, aesthetically speaking. (I'm only using 4 pins)

Another option, which also isn't so pretty, is just using the premade female->male jumpers, and trying to thread them nicely through a few tiny holes drilled in the side of the Pi case, but the height of the black female end makes that a bit difficult.

I've searched this forum, google images etc, and haven't had much luck finding examples of nice looking final product ideas.

Anything stopping you from soldering the four wires to the relevant points on the underside of the RPi?

I would get something like this and cut it in half. ;)

A really old PC might have one in. 8-)

Ones like this will work fine >>> http://www.ebay.co.uk/itm/40-Pin-Way-GP ... SwHnFV1m3V but they will mess with your mind and trick you into letting the smoke out of your RPi because of the way the cable wraps round the retaining clip.
Also it might be to bulky to fit in the case but it might be possible to remove the wrap over clip.

I repeat - Do be very careful with pin numbering.

I dunno, Fear? ;)

I hadn't even thought of that though, and upon looking at the Pi, I think you may be onto something.
That could end up pretty sweet actually, as I could hide the pathways to the underside of the protoboard as well.
FWIW, I had a bunch of IKEA Lack shelves left over from a bookshelf I had to cut down, and the little 12x10x1.5" black shelves are perfect for mounting a collection of protoboards onto.

Yeah, that's exactly where I am right now, I have the 40 pin ribbon cable sticking out of the side of the Pi, and am looking to get rid of it .... replacing it with something a little less obtrusive.
I think the 'undersoldering' may be the answer.

I used the perma-proto hats from Adafuit. Below is the link to the one I use and a photo of how I am using mine.

I'm soldering female headers to cheap chinese prototyping PCBs like these, so I can use them like a "hat" (minus the eeprom requirement)

That way I don't end up physically modifying the Pi itself (and with my soldering skills, or lack thereof, I can see myself destroying a few if I tried), and it's easy to switch to another one if I ever want to upgrade or replace the Pi.
