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.
