a first printed circuit board having a male edge connector, wherein the male edge connector comprises first and second side edges of the first printed circuit board wherein each of the first and second side edges includes one or more exposed electrical contacts at which one or more traces of the first printed circuit board terminate; and

a first magnetic coupler that is included on the first side edge of the first printed circuit board, wherein the first side edge, including the one or more exposed electrical contacts and the first magnetic coupler of the first printed circuit board, is adapted to be inserted into a female edge connector;

wherein the female edge connector is positioned atop a surface of a second printed circuit board, and wherein the female edge connector includes a second magnetic coupler and one or more pairs of electrical contacts that are positioned to opposing sides of a slot that receives the first and second side edges of the first printed circuit board;

whereby the one or more electrical contacts of the first and second side edges of the first printed circuit board contact the one or more pairs of electrical contacts of the female edge connector to establish one or more electrical connections, and wherein the first magnetic coupler establishes a first force of attraction with the second magnetic coupler of the female edge connector, to retain the first and second side edges of the first printed circuit board within the slot of the female edge connector.
