Temporary connections?

I bet once or twice in the past you wish that you could find a simple way to just hold a module with male headers like this Adafruit GPS module in the pin holes of a circuit board without soldering the pins so you can later take the module and put it elsewhere. Here I found a neat solution, wedging the module with some ESD foam. You get ESD foam pieces from buying ICs so they come for free and have some springy-ness. Then you put in between the module and the board and push in. The force from the foam will make the module form a wedge and there is enough strength to tlit the pins against the holes to make connection. Here are some photos:

The first photo shows the underside of my new phi-3 shield. The GPS module is supposed to be on the top side but unless I solder it to the shield, there is not enough space to make a wedge with the module while it is under the display. So I hang it below the shield board and stuck a piece of ESD foam between the module and the shield board. Here is a side view. You can’t see the foam, which is too dark but you do see the pins are all tilted and thus pushed hard enough to make electrical connection. I only recommend this on a temporary basis. Tomorrow the GPS module is going on another board, the SDI-12 + GPS USB adapter. I’ll solder this time.
