Having got the wrong ebay thing twice, it is time to ask for help...
I have a sticky keypad thing, but the wire isn't quite long enough to reach the controller. The cable ends with a female header connector thing (so the board has male header pins) - as in the attached image. What do I need to buy to add a bit of extension to this?
You can simply make your own extention, with basic connectors and some wire. Ebay , Radio Shack or some other electronic stores should have what you need.
