Abstract
An integrated circuit includes a nexus and a first, a second, a third, and a fourth circuit board. Each of the first and second circuit boards is coupled to opposing sides of the nexus, and each of the third and fourth circuit boards is coupled to opposing sides of the second circuit board. The integrated circuit is transitionable between a first, open configuration, in which the first, second, third and fourth circuit boards and the nexus are substantially coplanar, and a second configuration, in which the first, second, third and fourth circuit boards and the nexus are coupled to one another to define a cavity therein.
