1. A camera module comprising:
a printed circuit board comprising a first circuit board, a second circuit board, and a wire assembly, wherein the first circuit board defines a rectangular through hole configured for receiving the second circuit board, a gap is formed to space the second circuit board from the first circuit board, the wire assembly is positioned in the gap and provides an electrical connection between the first circuit board and the second circuit board;
a sensor chip mounted on the second circuit board;
a driving assembly comprising a transmission member and a shape memory alloy wire, wherein the shape memory alloy wire is mounted on the first circuit board and electronically connected to the first circuit board, the transmission member provides an electronical connection between the transmission member and the second circuit board so that the shape memory alloy wire drives the second circuit board and the sensor chip thereon to move in a plane of the printed circuit board;
a housing comprising an upper plate, a bottom plate, and a supporting member, wherein the upper plate and the bottom plate are mounted on either side of the first circuit board for sandwiching the printed circuit board, and the second circuit board is slidably supported on the bottom plate by the supporting member;
a lens;
a voice coil motor mounted on the upper plate, the voice coil motor being configured for receiving and driving the lens; and
a plurality of bulges arranged on the bottom plate or the supporting member, the plurality of bulges protruding from the bottom plate or the supporting member to the supporting member or the bottom plate, the plurality of bulges providing contact between the bottom plate and the supporting member.
