1. A flexible printed circuit board comprising:
a plurality of central portions positioned along a first direction;
hinge portions extending between adjacent central portions, each hinge portion foldable;
one or more tabs extending from each of the plurality of central portions in a second direction perpendicular to the first direction, the one or more tabs foldable relative to the central portion from which the one or more tabs extend;
a plurality of first surface pads located within each of the plurality of central portions;
a plurality of second surface pads located within each of the plurality of central portions on a side opposite from the plurality of first surface pads;
vias extending through each of the plurality of central portions, each via electrically connecting one of the plurality of first surface pads to one of the plurality of second surface pads;
lands located within one of the one or more tabs; and
electrical traces connecting the plurality of first surface pads and the lands;
wherein upon folding the flexible printed circuit board at the hinge portions, adjacent central portions can be vertically stacked and electrically connected by the plurality of first surface pads and plurality of second surface pads;
wherein the plurality of first surface pads of one of the plurality of central portions is configured to electrically connect to a transducer.
