Type-C The USB specification defines a comprehensive connectivity interface to address the trend towards miniaturization. Advantage 1 The mechanical components are small and thin, significantly superior to Mini USB and Micro USB, and support reversible insertion. Advantage 2 At the signal level, it supports high speeds of 5/10/20Gbps and is also compatible with speeds of 480Mbps or 12Mbps. Advantage 3 In terms of power, it allows for the classic 5V/3A, and also supports high voltage and high power of the PD protocol. Based on Type-C communication USB is also gradually being widely used in embedded fields such as microcontrollers. The simplest connection is a pair of signal lines and a pair of power lines. Only 4 wires are needed to achieve 480Mbps signal communication and 15W power transmission. It is simple, convenient, universal and low cost. Features Fast transmission speed, commonly 1.5Mbps/12Mbps/480Mbps; Built-in CRC check ensures data integrity; As a communication bus, it is addressable and scalable; Supports hot-swapping, dynamic connection and disconnection; Power and signals are transmitted together, and it supports high-voltage, high-power PD power transmission protocol; Unified interface and mechanical characteristics ensure high compatibility; The most commonly used interface for computers and mobile phones, supporting all operating systems.
