Usb Type C Otg Cable Pinout

The id pin can also have a 124 kω impedence to ground see below.

Usb type c otg cable pinout.

This will tell the otg device that it is allowed to draw current off vcc e g. Note down all the color of the cable and where it is connected to the actual usb connector on a page. Usb otg adapters hubs and card readers when an otg enabled device is connected to a pc it uses its own usb a or usb type c cable typically ending in micro b usb c or lightning plugs for modern devices. It was developed at roughly the same time as the usb 3 1 specification.

The usb type c specification 1 0 was published by the usb implementers forum usb if and was finalized in august 2014. The usb cable provides four pathways two power conductors and two twisted signal conductors. This will tell the otg device that it can not charge and hence must supply current to vcc but should act as a usb host. Note that a usb type c port could support usb 3 0 3 1 standards but the minimum feature set of usb type c doesn t include usb 3 0 3 1.

After the identification of the type of usb connector used on both ends note down the pinout diagram of that particular usb type. Since the connector is flippable a multiplexer is required to correctly re route the data on the employed differential pairs through the cable. I tend to do a fair amount of online shoppin. The 24 pin double sided connector provides four power ground pairs two differential pairs for usb 2 0 data bus though only one pair is implemented in a usb c cable four pairs for superspeed data bus only two pairs are used in usb 3 1 mode two sideband use pins v conn 5 v power for active cables and a configuration pin for cable orientation detection and dedicated biphase mark code bmc configuration data channel.

The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb device. I have been in the market for an otg cable otherwise known as a host cable for some time and i have found that the only places that seem to sell them are online only. The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors. Charge its battery as well as act as a usb host.

Make a usb otg host cable. First of all find out the type of usb connector used in the cable. Rough sketch diagram. This is not a problem half the time.
