Breadboard-to-Arduino wiring with flat flex cable assemblies? I want to wire Arduino Due connectors to a breadboard 8-at-a-time, so they're easier to remove and more reliable.

I tried these Flat Flex Cable Assemblies (FFC assemblies) terminated with "solder lugs" from Digi-Key, but the pins are just a little too short to penetrate the Arduino connectors well.  Similarly they barely reach into to the breadboard contacts, so they tend to fall out.  Anyone find a workable product for this?


 

This solution is good but requires a lot of manual soldering.  Looking for prepackaged.
Search for male-male jumper wire. Some of what you'll find is individual wires but there are also many that are connected together and you can rip off the width you need.

Here's one from Adafruit but there is no shortage of them on ebay/amazon.
