1. A vehicular camera, the vehicular camera comprising:
a lens holder comprising a lens;
wherein the lens comprises a plurality of lens optics;
a plurality of printed circuit boards;
the plurality of printed circuit board comprising at least a first printed circuit board and a second printed circuit board;
wherein the first printed circuit board comprises a first side and a second side opposite the first side that is separated from the first side by a thickness dimension of the first printed circuit board;
wherein the second printed circuit board comprises a third side and a fourth side opposite the third side that is separated from the third side by a thickness dimension of the second printed circuit board;
wherein the first and second printed circuit boards are stacked and overlap one another;
wherein circuitry disposed at the first printed circuit board is electrically connected with circuitry disposed at the second printed circuit board via board-to-board electrical connection;
wherein the circuitry disposed at the first printed circuit board comprises an imaging sensor, and wherein the imaging sensor is disposed at the first side of the first printed circuit board;
wherein the imaging sensor is operable to capture image data;
wherein the first side of the first printed circuit board faces the lens;
wherein the lens is optically aligned with the imaging sensor;
wherein thermally conductive material is disposed between the second side of the first printed circuit board and the third side of the second printed circuit board, and wherein the thermally conductive material is in thermally-conductive contact with the second side of the first printed circuit board and is in thermally-conductive contact with the third side of the second printed circuit board;
a rear housing, the rear housing comprising an electrical connector portion; and
wherein the electrical connector portion of the rear housing comprises an electrical plug connector.
