Usb otg cable wiring diagram. In accordance with usb otg wiring diagram there are just four wires used inside the cable. Typically it utilizes black black red and white cable colors. Black wire serves as floor exactly like in any other apparatus. Pinout of usb micro plug to usb standard receptacle for use with usb otg on the goallows portable devices such as cell phones which support otg to connect directly to other devices such as usb keyboards mice and mass storage devices. The red one is to get sure wire with dc ability of 5 liter. The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb device.
Black wire serves as ground just like in any other apparatus. The red one is to get sure wire with dc ability of 5 volts. Before wiring usb you need to know the pinout diagram of usb. A lot of people wonder why have micro usb 5 pins instead of 4. Typically it uses black black white and red wire colors. The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors.
I made another schematic how you should wire things up so the usb will work as a host or otg mode. Actually the extra pin or pin 4 is typically not connected in the normal usb cable but if it is connected to ground pin the phone will turn in a host mode and will be able to read. The usb cable provides four pathways two power conductors and two twisted signal conductors. Below is the figure showing the pinout diagram of the usb micro b and usb a wiring diagram. This cable is most commonly used in mobile charger for charging mobile phones and as a usb data cable to connect mobile devices to tranfer files and images between personal computers and phones.
