The Universal Serial Bus (USB) is a proven connectivity system. Pin 1, which is the VBUS, is used to power any connected peripheral by supplying a +5-V voltage from the USB host. Pin 2 is the negative data terminal denoted as D– (DM), while Pin 3 is the positive data terminal denoted as D+ (DP).
How many wires does USB C have?
four wires
The Type-C connector was designed to enhance smaller device design and is physically smaller than previous USB connectors; openings are approximately 8.4mm by 2.6mm. This connector has come a long way from its ancestor with four wires.
How can you tell the difference between positive and negative wire?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
