Like all connectors, all types of USB connectors have male and female types, making sure you connect your devices in the right direction. Check out the table below for the full USB pinout. Two of these wires are for power supply, while the other two are for differential data signal pairs. The USB has four shielded wires that work as pins. So, in this article, we’ll explain everything about the USB and give different USB examples for your circuits. However, that’s just the surface of it all. Also, there are cases where you can add additional USB network hubs to create a tree connection structure. Normally, the architecture of a USB system includes a host controller, USB ports, and a wide variety of devices. USB stands for Universal Serial Bus and has since replaced its predecessors (FireWire, RS-232 serial, and even parallel) as the primary interface for connecting a host to a device.

Nowadays, it’s easy to complete projects that involve creating a physical connection between a host controller and several other bus-powered devices because of the USB interface.
