Abstract
In accordance with embodiments of the present disclosure, a circuit board may include a connector configured to electrically couple a device to the circuit board. The connector may include a conductive element configured to be electrically coupled to a first voltage and a detection pad configured to be electrically coupled to a second voltage via a resistor, such that when a device pin of a device is electrically coupled to the conductive element, the detection pad is electrically coupled to the conductive element via the device pin.
