Magnetic Charging Cable With Storage Function And Easy Fold Material

The USB interface has 4 pins, which are USB power (usually 5V), USB data line +, USB data line and ground. USB has two specifications, namely USBI.1 and USB2.0.

The transmission rate of the high-speed mode of USBI.1 is 12Mbit/s, and the transmission rate of the low-speed mode is 1.5Mbit/s, 1Mb/s=8 Mbit/s, 12 Mbit/s=1.5 MB/s.

The USB2.0 specification is evolved from the USBI.1 specification. Its transmission rate has reached 480Mbit/s, which is converted into MB to 60MB/s, which is sufficient to meet the rate requirements of most peripherals. The "Enhanced Host Controller Interface (EHCI)" in USB2.0 defines an architecture compatible with USB1.1, which can drive USB.1 devices with USB2.0 drivers. In other words, all devices that support USB1.1 can be used directly on the USB2.0 interface without worrying about compatibility issues, and accessories such as USB cables and plugs can also be used directly.

USB2.0 standard further increases the interface rate to 480Mbit/s, which greatly shortens the transmission time of video and audio files in LCD color TVs.
