1. An auto focus digital camera module, comprising: a housing; an image sensor within the housing; an optical train within the housing aligned with the image sensor defining an optical path and comprising multiple lenses including at least one movable lens coupled to a lens actuator configured to move the at least one movable lens along the optical path to focus a subject onto the image sensor that is disposed within an auto-focus range of the camera module; a flexible printed circuit (FPC) including a sensor segment coupled to the image sensor to power the camera module and to carry electronic signals that include digital images captured by the image sensor; and wherein the FPC further comprises an extension segment that includes electrical contact pads configured to electrically couple to lens actuator contact pads to carry lens actuator control signals when the FPC is folded around the camera module from the sensor end to the object end.
