I'm trying to identify what this type of connector is. The first image is the male connector, attached to a flex ribbon. It has 20 pins on each side. I thought it was an FFC connector, but can't find anything remotely like it in Digikey FFC connectors. The closest match I can find is an Apple LCD flex cable "grade R" replacement. Any ideas? Thanks!
They're "board to board" connectors, but are sometimes used on FPC as well - especially for things like TFT.
It's not quite identical, but it should give you a starting point.
This is one used on the Picadillo-35T board which looks a closer match:
Unfortunately I don't have a model number for that, though with a bit of pestering I may be able to find out.
