There are two categories of USB connectors: What are the different types of USB? Complete listĪ USB may be classified on the basis of a connector type, cable/port, and version/standard/color. So, let’s start our discussion by listing out all the types of USBs. So, in this article, we will discuss all the USB types that are available and the differences between them. But, due to a wide range of USBs certain doubts and confusions may arise like whether USB 3.0 and USB C are the same or not. With time, the USB cables have evolved and now they have many variants. It is used for a range of items, including smartphones, computers, cameras and games.Almost every device that we use nowadays requires a USB cable that connects it to other electronic devices. USB-C is also bi-directional, meaning the power can flow from either direction. It is interchangeable and is more versatile than its predecessors and has been the leading USB technology since 2014, replacing USB-A, USB-B, HDMI, 3.5mm audio jacks and the DisplayPort audio/video connectors. USB-C:The oval-shaped 24-pin connector was developed as a replacement for previous connectors. The 3.0 is the standard plug for most laptops but not as rapid with data transfers as the latest USB. USB 3.0:The rectangular-shaped USB 3.0, which was released in November 2008 is backward-compatible and able to accommodate plugs before version 3.0. Micro USB connectors are approximately 50-60 percent smaller than mini connectors and replace Mini USB in many new Smartphones. Micro USB:In January 2007, the USB-IF approved what was then the most space-conscious connector size: Micro USB. Unlike standard A and B connectors, Mini A and B have very similar shapes however, it’s possible to distinguish one from the other by the upper halves of their vertical edges: Mini A’s sides are straight, but Mini B’s are rounded. Mini USB:Developed for use with small, portable peripherals like digital cameras, cell phones and MP3 players, Mini USB connectors feature a more compact and space-efficient design than standard USB connectors. Standard USB connectors are typically used with, well, “standard” peripheral devices like printers, keyboards, computer mice and scanners. Standard-size “A” connectors have a long and extremely narrow rectangular shape (approximately 4mm x 12mm), while standard “B” connectors are still oblong, but with shorter and wider proportions (at roughly 7mm x 8mm, they’re closer to being square). Standard USB: Standard is the original USB connector size, and the largest of the bunch. Here’s a general breakdown of how connector styles differ by size class, and the applications each is used for: In addition, USB plugs fall into three different size ranges: standard, mini, and micro. USB connectors - and, by extension, USB ports - can be found in two different styles: type “A” (for hosts and USB hubs) and type “B” (for peripheral devices). HOW MANY TYPES OF USB CONNECTORS ARE THERE? USB-C is compatible with larger electronics and can support devices at a speed of 40 Gbit/s. SuperSpeed: This category was developed with USB 3.0, with SuperSpeed+ within version 3.1.USB 3.0 allows for quicker connections, with USB 3.0 at 5 Gbit/s, 3.1 at 10 Gbit/s and UUSB 3.2 at 20 Gbit/s.High Speed: “High speed” USB devices run at 480 Mbit per second and require a 2.0-rated USB cable.And even though the data transfer speed is higher, Full Speed - like Low Speed - transmits equally well via 1.1 or 2.0 USB cables. Since this is such a common bandwidth requirement, all USB hubs on the market have been designed to support Full Speed. Full Speed: Devices labeled “Full Speed” need a signal rate of 12 Mbit per second.Joysticks, keyboards and computer mice are a few common examples of Low Speed devices. Low Speed: The “low speed” rating indicates that a device requires minimal bandwidth (1.5 Mbit/s) to function, so it can be used in conjunction with either 1.1 or 2.0 USB cables.In addition to the bandwidth classifications listed above, USB devices can also be labeled in the following “speed” categories, which specify the amount of bandwidth they need to operate: USB 2.0 is backward compatible with the lower data transmission requirements of 1.1, but the substitution can’t be reversed 1.1 just can’t deliver the rate of data transfer that USB 2.0-rated devices need. Generally speaking, USB cables are classified into one of two different bandwidth groups: 1.1, which transfers data at a maximum rate of 1.5 Mbit per second, and 2.0, with a 480 Mbit per second data transfer rate.
