1. A camera assembly, comprising:
a first sub-assembly, comprising:
a lens assembly having an optical axis;
a first printed circuit board (PCB) including a first surface and a second surface disposed opposite the first surface; and
an image sensor attached to the first surface of the first PCB, the optical axis of the lens assembly remaining aligned with a center of the image sensor;
a second sub-assembly removably attached to the first sub-assembly, the second sub-assembly comprising:
a second PCB including a first side surface and a second side surface disposed opposite the first side surface, wherein the second PCB is offset a distance from the first PCB; and
a flex circuit electronically connecting the first PCB and the second PCB, wherein the flex circuit is moveable between an assembled state, where the first sub-assembly is assembled with the second sub-assembly and the first PCB is arranged a first distance from the second PCB, and a disassembled state, where the first sub-assembly and the second sub-assembly are detached from each other and the first PCB is arranged a second distance from the second PCB, the second distance being greater than the first distance, and wherein, when in the disassembled state, the flex circuit remains interconnected to the first PCB and to the second PCB;
a first foam block attached to the second surface of the first PCB extending in a direction toward the second PCB; and
a second foam block attached to a first side surface of the second PCB extending in a direction toward the first PCB, wherein a portion of the flex circuit is arranged between the first foam block and the second foam block.
