Usb To Uart Cable Pinout

The basic usb pinouts for the connectors are given in the table below.

Usb to uart cable pinout.

The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors. The usb 2 0 hi speed to uart cable incorporates ftdi s ft232h usb to uart interface ic device which handles all the usb signalling and protocols the cable provides a fast simple way to connect devices with 3 3 volt digital interfaces to usb. The cables provide a fast simple way to connect devices with a ttl level. The chip handles all the protocol of converting usb data to uart serial data.

For full details features and enhancement descriptions of the ft232h please refer to the ft232h datasheet. Apart from the usb connector pinouts the table also gives the wire colours used within the cables. A range of cables are available offering connectivity at 5v 3 3v or user specified signal levels with various connector interfaces. All cables feature an ftdi ft232r device integrated within the cable usb type a connector which provide access to uart transmit tx receive rx rts cts vcc 5v and gnd connections.

Usb type a b pinouts connections. Usb a b 2 0 and 3 0 cable pinout. The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb device. Ftdi cable usb to rs232 converter pinout click the image to enlarge it ftdi cables are the family of usb to ttl serial uart converter cables and they are incorporated with ft232r ic.

The usb cable provides four pathways two power conductors and two twisted signal conductors. Inside the big usb plug is a usb serial conversion chip and at the end of the 36 cable are four wire red power black ground white rx into usb.
