USB interface versions
Hardly anyone remembers today, that the first really popular version of the discussed link was USB 1.1. Shortly afterwards USB 2.0 came to computer devices and for several years it reigned among almost all types of computer peripherals - although with equal success. It appeared in cell phones and many other portable devices, audio equipment, musical instruments or measuring, industrial, medical and automotive equipment. Another breakthrough was the introduction of the super-fast USB 3.0 interface in 2013 - the speed of the data bus increased to over 600 MB/s, which allowed to transfer data (e.g. between a computer and an external drive) at almost incredible speeds. The USB 3.1 and USB 3.2 standards introduced in the following years increased the transfer speed up to 2500 MB/s. The increase in transfer rate is also followed by changes in the types of sockets and plugs used, and this forces the use of appropriate USB adapters.
Plugs, sockets, adapters... Micro USB to USB adapter and many, many others
A characteristic feature of USB, which distinguishes this interface from other computer buses, is the variety of connectors - both sockets and matching plugs. The most common in desktop computers, laptops, and other USB host-mode devices (such as digital oscilloscopes) is the 4-pin, flat USB A connector. Larger peripherals (printers, scanners) have a B socket (resembling a square with two corners beveled). Smaller devices (e.g. digital cameras) for many years were equipped with a mini USB socket, but later it was replaced by the very popular micro USB socket, often serving only as a power socket (e.g. in power banks or mini computers Raspberry Pi). What is important, USB cables and adapters compliant with the official USB standard prevent incorrect connections, e.g. the juxtaposition of two devices working in USB host mode. The matter became a little more complicated after the introduction of the universal USB C connector, as well as after the popularization of USB OTG ports, which allow one device to act as both the host and the terminal device.
USB adapters in the offer of Botland store
In our offer you will find a wide range of USB adapters, allowing you to easily connect different compatible devices. For smartphones and tablets that support USB OTG mode we have small adapters, allowing for example to connect to the mobile device pendrive or external drive. The problem of too short cables will eliminate the USB A-A extension cables with a length of 1.8 m and 3 m. We also have a number of off-the-shelf USB adapters available - they are used to power devices using standard DC 5.5/2.1 mm plugs, but they also make it easier to lead out the power line (to crocodiles) or all four lines of the USB cable (to a goldpin plug).
