I have a TNC-Pi & Pi model B mounted inside a HDMIPi, with the gpio pins linked with a 300mm ribbon cable.
I will soon upgrade to a Pi 2, so will need a 40-pin to 26-pin ribbon cable.
The only cable I can find is Adafruit's, but it won't be long enough.
Does anyone make such a cable that is 300mm long?
Thanks,
Paulie
