Several cores generally refer to the cable, which refers to the existence of several wires insulated from each other inside the insulating outer skin, and several cores are genus, if they are not insulated from each other, how many cores are counted as one core. So how many cores is the USB cable?
USB is a commonly used PC interface, it only has 4 wires, that is to say, there are 4 cores. Two power supplies and two signals, so the signal is transmitted serially, USB interface is also called serial port, USB2.0 speed can reach 480Mbps, can meet a variety of industrial and civil needs.
The general arrangement is: red, white, green, and black from left to right.
Red -USB Power Supply: Marked with the words -VCC, Power, 5V, 5VSB.
White-USB cable: (negative)-DATA-, USBD-, PD-, USBDT-.
Green-USB cable: (positive)-DATA+, USBD+, PD+, USBDT+.
Black-ground: GND, Ground.
The USB cable is a few cores to explain to you here, I hope it can help you. USB cable cores are used in different colors to distinguish the wires, generally more than three cores of the cable have a green/yellow two-color wire, specified as the color of the grounding wire.
