Stupid question: permanent connections to existing pins on add-on


I know I've asked similar questions in the past, but I'm still confused. For a component like this:

..what's the best way to wire this up into a permanent project? Solder bare wires to the pins? Use the wires with the sockets on them (that are easily put on and removed)? Wire-wrapping? There's gotta be a standard way here, just wanna do it right.


The question is not clear. What is permanent? Duration of a senior design project in college or permanent installation in a museum or maybe outdoors? For a design project, jumper wires with female headers will suffice. If you want more permanent solution, you should desolder the male headers and replace with wires or a socket with polarizing key and locking tab.

Permanent in the sense that I'd like to make a contraption for my home, put it in an enclosure, and have it be running for a long time as if it was a product that I bought from a store, without worrying that the wires are going to come loose. What is a polarizing key and locking pin? Assuming I don't want to de-solder, should I use jumper wires with female headers and use electrical tape to hold the wires in place?

a non destructive solution could be a blank arduino shield with soldered pins (proto shield) and a connector cable between shield and your ethernet unit. you could use cable fixer too for fix the unit on the shield. this solution is stable, nondestructive and components can easily be changed if they hav a defect

Talking about non-destructive, you can use wire wrap between these pins and your arduino (use a shield with pins soldered).

A standard 10-way IDC ribbon cable will connect quite nicely to that and it will be neat, it will be reasonably secure as well. If you want really secure unsolder that header and replace with a locked/ejector version.


IDC connector Ribbon cable

You can make a neat solution using ribbon cables with the correct female connectors on, and plastic housings which accept the connectors. The housing are available in various sizes at minimal cost. I use these routinely in stationary installations and haven't ever had any problems with the connectors pulling loose, but if that was an issue it would be trivial to secure it with a cable tie, tape, glue etc. A latching connector seems to be overkill for something that doesn't need to be disconnected in normal operation and IMO it would be a pretty unusual project to justify the effort to unsolder headers etc to install one.
