A vehicular camera module includes a camera having an image sensor and a lens. The image sensor is disposed at a first printed circuit board, and a second printed circuit board is in board-to-board electrical connection with the first printed circuit board. Board-to-board electrical connection between the first and second printed circuit boards is via a multi-wire ribbon connection. A housing houses the first and second printed circuit boards. The housing is configured for mounting at a windshield of a vehicle and, with the vehicular camera module mounted at the windshield of the vehicle, the camera has a field of view external of the vehicle. With the vehicular camera module mounted at the windshield of the vehicle and responsive at least in part to processing by an image processor of image data captured by the image sensor, an object in the field of view of the camera is detected.
