The table below helps give an overview of the various types and formats. Besides some active cables utilize a re driver chip to strengthen the signal and compensate for the losses incurred by the cable etc. Product title poweradd 3 outlet surge protector 3 usb ports power.

It has become the standard connection method for wide variety of devices. It uses 4 shielded wires. Usb 1 and usb 2 type a ports have just four pins internally. Maximum length of cable is about 5 m for awg20 and 0 8 m for awg28 cable.

Types a and b have 4 pins within the connector mini and micro a and b connectors generally have five pins. Power cables that comes with power banks are sometimes of this type. The usb cable provides four pathways two power conductors and two twisted signal conductors. Usb is a serial bus.

The 24 pin double sided connector provides four power ground pairs two differential pairs for usb 2 0 data bus though only one pair is implemented in a usb c cable four pairs for superspeed data bus only two pairs are used in usb 3 1 mode two sideband use pins v conn 5 v power for active cables and a configuration pin for cable. Some usb cables only carry power lacking the wiring for data transmission. Two for data and two for power. Usb type a usb type b mini a mini b micro a micro b and micro ab.

In these cases we can power the circuitry inside the cable by applying a 5 v 1 w power supply to the vconn pin. Image courtesy of microchip. As a result there are many usb connector types. Two for power 5v gnd and two for differential data signals labelled as d and d in pinout.

The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors. In a usb data cable data and data signals are transmitted on a twisted pair with no termination needed. Pinout of usb and layout of 4 pin usb a or usb b plug connector and 4 pin usb a usb b mini usb jack connectorusb universal serial bus designed to connect peripherals such as mice keyboards scanners digital cameras printers hard disks and networking components to pc. 99 list list price 25 99 25.

Usb 3 type a ports have nine pins in total but are completely backwards compatible. The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb device.
