Micro Usb Pin Assignment
Only products that pass have the right to license the USB-IF Logo.A noteworthy point about the USB type C spec is that the connectors are reversible; flip one upside down and it will still fit in a type C socket and function just fine.The USB connectors also operate over -25 to 85°C and have Ro HS compliance.One reason USB 3.0 is becoming widely used is its capability for handling power.These include USB 3 Type-B, USB Type-C, and USB 3 Micro-B. Of course, USB 2.0 peripherals could draw power from the host port and function without an external power supply.USB 3.0 includes something called the Powered B (or Powered USB) connector.Micro USB has been superseded by USB Type C on many new products.See Mini USB, USB Type C, USB 3.0, USB OTG and USB.
The Powered B male plug is only available hard-wired to devices that specifically support it.
The current version of the standard, USB 3.1, extends the performance range to 1 GB/sec.
Another point to note about speed is that USB 3.0 ushered in “Super Speed” 5 Gbps, and the USB 3.1 maximum rate of 10 Gbps is called “Super Speed Plus.” USB 3.1 peripherals share bandwidth through a protocol that lets peripherals be attached, configured, used, and detached while the host and other peripherals are in operation.
USB Type-C connector and cable is reversible (the connector has no “up” side) and the cable is reversible (either end can plug into any device).
The spec also provides more internal wiring than USB 3.1 strictly needs, allowing it to work with other standards such as Display Port.
