USB Mini

Mini USB connectors, smaller than the standard USB B, are designed for peripherals needing a compact connection. With 5 pins, including an ID pin, they support USB On-The-Go (OTG), allowing devices like mobile phones to act as USB hosts. Originally popular in early mobilephone, USB Mini B has shifted towards use in digital cameras as devices have trended towards even smaller connectors like micro USB. Today, Mini B serves as a legacy connector, mainly found in specific devices and no longer common for new products.

USB Mini A connectors, though less common than Mini B, also provided a compact solution for mobile devices and peripherals. Mini A connectors were used in some early mobile devices and portable gadgets. However, like Mini B, the trend towards smaller and more efficient connectors like micro USB and USB-C has made Mini A connectors less prevalent in modern devices.
