A vehicular camera module includes a main circuit board electrically connected with an imager circuit board via a flexible ribbon cable. Electronic circuitry disposed at a main PCB of the main circuit board includes an image processor. With the imager operated to capture image data, captured image data is provided via the flexible ribbon cable to the electronic circuitry disposed at the main PCB of the main circuit board. The electronic circuitry disposed at the main PCB of the main circuit board includes an electrical connector configured for electrical connection to a connector of a vehicular wire harness. Electrical components disposed at a first side of the main PCB of the main circuit board, electrical components disposed at a second side of the main PCB of the main circuit board, and the electrical connector are electrically operatively coupled together by conductive traces and vias of the main PCB.
