So, the complexity of USB Type-C became more closer to the HDMI connectors.ĭifference between a USB Type-C and a micro-USB connector is in the difference of the pins (and wires). USB-C is a 24-pin USB connector system, which uses rotationally-symmetrical connector. In this background, we got the Type-C connector. USB 3.0 cables were not backward compatible. It had (and has) a Type Micro B version with that extra connector extension. USB 3.0 added four new pins and an extra ground signal. USB Micro B was good enough till USB 3.0 came. It included the contact springs to ensure a tighter connection without making the connector longer. USB Micro B introduced a thinner, rugged connector, with more duty cycles. USB Type-C is Completely a Different Concept One is the USB Micro B connector and the second is the “On the Go (OTG)” protocol. The USB standard forum and the small device manufacturers engineered two improvements. That was enough great for a PC for a mouse or keyboard. One host device (PC) could talk to up to 127 devices per port via hubs. USB was originally designed as a Host/Target protocol.
The thing that was added in the Mini-B generation was USB On-the-Go (OTG). It has two digital signal pins and power, ground pins that we find on Type B connectors. The USB Mini-B was adopted for much smaller devices. USB Type B was designed for the larger, desktop-sized devices. USB came as a replacement for the large connectors to replace the serial ports, parallel ports, the port for PC mouse and keyboards. USB-C is not like the classic USB connectors (including the microUSB and MiniUSB connectors). USB-C Connector (USB Type-C is the official name) Increasingly Being Used in Modern Smartphones and Other Computing Devices.
