Patent attributes
Circuit blocks are provided. A circuit block may include a substrate and at least one electrical component mounted on the substrate. The circuit block may also include a non-conductive frame coupled to the substrate, and at least one post coupled to the substrate and extending from the substrate and through at least a portion of the frame in a first direction substantially perpendicular to the major surface of the substrate. Moreover, the circuit block may include a contact coupled to a second, opposite surface of the substrate and including a corner section projecting outwardly from the frame and extending in at least two directions substantially perpendicular to a longitudinal axis of the at least one post. The block may also include at least one magnet positioned proximate the flexible corner section of the contact and configured to magnetically attract at least one other circuit block.
