1. An electronic device, comprising:
a first circuit board;
a second circuit board;
an interposer circuit board defining a walled interface mechanically attaching the first circuit board to the second circuit board;
one or more electronic circuit components positioned within the walled interface and mechanically attached to one of the first circuit board or the second circuit board; and
an electronic circuit interface component mechanically attached to the first circuit board outside the walled interface and electronically coupled to the one or more electronic circuit components;
wherein the interposer circuit board has an exterior perimeter and defining an aperture having an aperture perimeter, the interposer circuit board electrically coupling the first circuit board to the second circuit board between the exterior perimeter and the aperture perimeter.
