Abstract
Reversible connector orientation detection circuitry, reversibly connectible devices having multiple device portions, and methods for determining a connection orientation of multiple device portions of a hardware device are provided herein. A hardware device can include a first device portion and a second device portion. A first resistor can be in a first side of the first device portion. A second resistor can be in a first side of the second device portion, and a third resistor can be in a second side of the second device portion. Connection of the first device portion to the second device portion in different orientations creates, through the resistors, different voltages that can be compared by a digital logic device to indicate orientation. The compared voltages are within either a low voltage range below a digital logic low threshold or a high voltage range above a digital logic high threshold.
