Abstract: A printed circuit board has a first plurality of pin receptors configured to receive a first type of keyboard controller and a second plurality of pin receptors configured to receive a second type of keyboard controller. The first plurality of pin receptors are in the form of a square which defines an outer boundary of an area wherein the second plurality of pin receptors are formed. The second plurality of pin receptors are also in the form of a square. Equal numbers of pin receptors are provided on each side of each square, and the corresponding sides of the two squares are mutually parallel. Conductive traces are formed between corresponding pin receptors of the first and second plurality of pin receptors. The pin receptor configuration allows two different types of keyboard controllers to be used with the printed circuit board without requiring additional space on the printed circuit board.

Abstract: A printed circuit board having a footprint that is capable of receiving one of two electronic components having differing pin configurations. The footprint includes a first and a second common pin receptor arranged about a first axis. The first and second common pin receptors are configured to receive a first and a second pin on either of the electronic components. The footprint also includes a third pin receptor that is positioned along the first axis so as to be interposed between the first and the second common pin receptors and is configured to receive a third pin receptor of the first electronic component. The footprint also includes a fourth pin receptor that is positioned along a second axis, that is orthogonal to and intersects the first axis at the location of the third pin receptor. The fourth pin receptor is configured to receive a third pin of the second electronic component.
