50-pin 0.5mm FFC / FPC Extender
This 50-pin FFC / FPC Extender is very simple. It lets you connect two 50-pin 0.5mm pitch FFC (Flexible Flat Cable) / FPC (Flexible Printed Circuit) cables end-to-end and extend the length.
Note that pin 1 of one cable is connected to pin 50 of the other so you need to use a cable that has contacts on the same side (type A cable)
Carefully pry the two ears of the connectors, plug the cables with contacts pointing up, and then push the ears back in for a solid connection.
