What is a USB connector?
USB is popular for its compatibility with many platforms and operating systems, low implementation costs, and ease of use. Connectors come in many shapes and sizes and serve a variety of functions.
USB (Universal Serial Bus) is an industry standard developed in the 1990s for connectivity between computers and peripheral devices.USB is popular for its compatibility with a wide range of platforms and operating systems, low implementation costs, and ease of use.
The USB-IF (Universal Serial Bus Implementers Forum, Inc.) is a support organization and forum for the advancement and adoption of USB technology. It was founded by the companies that developed the USB specification and has more than 700 member companies. Current board members include Apple, Hewlett-Packard, Intel, Microsoft, Renesas Electronics, STMicroelectronics, and Texas Instruments.
Every USB connection is made using two connectors: a socket (or receptacle) and a plug.The USB specification addresses the physical interfaces and protocols for connecting devices, transferring data, and powering them.The USB connector type is denoted by a letter that indicates the physical shape of the connector (A, B, and C), and a number that indicates the speed at which the data can be transferred (e.g., 2.0, 3.0, 4.0). The larger the number, the faster the speed.
Specifications - Letters
USB A is thin and rectangular in shape. It is probably the most common type and is used to connect laptops, desktops, media players and game consoles. They are primarily used to allow host controllers or hub devices to provide data or power to smaller devices (peripherals and accessories).
USB B is square in shape with a beveled top. It is used by printers and external hard drives to send data to the host device.
USB C is the newest type. It is smaller, has an oval shape and rotational symmetry (it can be connected in either direction.) USB C carries data and power over a single cable. It is widely accepted and will be required for battery charging in the EU from 2024.
