TTL-232R-3V3 cable is a family of USB to TTL serial UART converter cables incorporating FT232RQ USB to Serial UART interface IC device which handles all the USB signaling and protocols. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB. Each TTL-232R cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB connector end of the cable. The other end of the cable comes with the 6 pin SIL, 0.1 pitch connector. The cable supports the FTDIChip-ID, with a unique USB serial number programmed into the FT232R. This feature can be used to create a security or password protected file transfer access using the cable.


  • USB side of the cable is USB powered and USB 2.0 full speed compatible
  • 1.8m long and supports a data transfer rate up to 3Mbaud
  • Onboard FT232RQ provides single chip USB to asynchronous serial data transfer interface
  • Entire USB protocol handled by the electronics in the cable USB
  • Connect directly to a microcontroller UART or I/O pins
  • Internal EEPROM with user-writeable area
  • 3.3 V output allows external logic to be powered from the USB port
  • Low USB bandwidth consumption
