[TriEmbed] Take 2 - 0.5mm connector WITH PICTURES

[Carl Nobile]

The one on the Blue board does not take a ribbon cable; it is definitely a
flat cable. The white board seems to take a ribbon cable with an
appropriate connector.
Ribbon and flat cables are two different beasts. Ribbon cables are usually
made of stranded wire and are often, but not always, multi-colored. Flat
cable, on the other hand, is just that the wire is not stranded, and it's
made of many pieces of flat wire next to each other. A friend of mine who
passed away many years ago invented flat wire. His company was Flat Wire
Inc. If my memory serves me.

What are you actually trying to do? If it's mating the two, I still think
an intermediate board would be necessary.
