USB Standards - Comparison

USB, stands for Universal Serial Bus, was designed to standardize the method peripherals are integrated with PCs. It enables communication as well as carrier power. It has largely replaced interfaces such as parallel ports and serial ports.

The USB standard started with USB 1.0 and now are at USB 3.2. We can notice exponential increase the bandwidth that each new variant can support. The most popular standards in USB are the USB 2.0 and the USB 3.0. The USB 2.0 supports a bandwidth of 480Mbps whereas USB 3.0 supports a bandwidth of 5Gbps.

Comparison table based on bandwidth


We can also compare the standards based on the connectors


When we design a USB camera, we need to also understand the maximum capability of the sensor, how much bandwidth required, make the selection of the standard that can reflect the sensor performance and also other parameters such as size and cost, choose the right connector according to the design requirements.
