Abstract: A circuit board having at least one operational characteristic. The circuit board includes a surface and a plurality of conductive pads accessible from the surface and for electrically coupling electrical components to one another. Further, the circuit board includes a plurality of attachment pads accessible from the surface. Lastly, the circuit board includes at least one identification component attached to at least one of the plurality of attachment pads, wherein the identification component comprises a marking for identifying said at least one operational characteristic. The identification component may or may not include an electrical characteristic. If an electrical characteristic is included, an in-circuit tester may be used to measure the electrical characteristic of the identification component and, thus, determine the identifier given the measurement. As an alternative, the measurement may be used to ensure the correct type of identification component is installed on the circuit board.
