One of my friends gives me two units shown in the picture, one of them had broken FPC connector. It looks like a Kinect early prototype, but I'm not sure about it. I don't have any information about these unit yet, anyone know please tell me. It need external power, the fan spin, but that's it, no other action, maybe voltage not high enough? I took apart one of these units, it seems like a new kinect, but I'm not sure. This company bought by Microsoft in 2010 The date printed on the PCB bords shows that the units comes out no earlier than 2010, so.........any ideas?
