The TTL-232R-5V-PCB is a USB to TTL serial UART converter PCB incorporating FTDI’s FT232RQ USB to
Serial UART interface IC device which handles all the USB signalling and protocols.

The PCB provides a fast, simple way to connect devices with a TTL level serial interface to USB.
Each TTL-232R_PCB contains a small internal electronic circuit board, utilising the FT232R plus a USB
type-A connector

The PCB is USB powered and USB 2.0 full speed compatible. Each PCB supports a data transfer rate up to
3 Mbaud and 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


  • TTL-232R_PCB provides a USB to TTL Serial UART interface.
  • On board FT232RQ provides single chip USB to asynchronous serial data transfer interface.
  • Entire USB protocol handled by the electronics on the PCB.
  • Connect directly to a microcontroller UART or I/O pins.
  • UART interface support for 7 or 8 data bits
  • Data transfer rates from 300 baud to 3 Mbaud at TTL levels.
  • Internal EEPROM with user writeable area.
  • Support for FT232R FTDIChip-ID™ feature for improved security.
  • PCB is USB Powered - no external supply required.
  • +5 V or +3.3 V output allows external logic to be powered from the USB port.
  • Low USB bandwidth consumption.
  • UHCI / OHCI / EHCI host controller compatible.
  • USB 2.0 Full Speed compatible. 
  • -40°C to +85°C operating temperature range.
