Usb Type A Pin Diagram
The interface is suitable for one of kind and small scale designs as well as mass produced standard peripheral types.
Usb type a pin diagram. Usb 2 0 has a maximum signaling rate of 480 mbit s and usb 3 0 has a usable data rate of up to 4 gbit s 500 mb s. Who knows what the future reserves. Usb type a usb type b mini a mini b micro a micro b and micro ab. Usb 2 type a pinout.
Usb 1 0 and usb 2 0 are. Usb 3 0 combines usb 2 0 bus and new superspeed bus with transfer rate up to 5 0 gbit s which is about ten times faster than the usb 2 0 standard. Usb 1 0 and usb 2 0 shares same connector pinout usb 3 0 pinout and usb type c features new connectors with their own pinouts. The pinout diagram for the micro usb type b very similar to usb type a except for the last two pins 4 and 5.
As a result there are many usb connector types. An usb device must indicate its speed by pulling either the d or d line high to 3 3 volts. Also it is the same for micro usb type a and micro usb type b. Usb 3 2 released in 2017 added superspeed transmission rate up to 20 gbit s and multi link modes.
Types a and b have 4 pins within the connector mini and micro a and b connectors generally have five pins. Later the usb c type was introduced to provide a more robust system with better data transfer performance. Usb 3 0 connectors are. Half duplex can either send or receive data power usage up to 500 ma per one host controller.
The pin no 1 is 5v acts as a source to the device or source from the device.
