Product Overview

The TTL-232R-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 PCB. The TTL-232R_PCB requires USB drivers, which are used to make the FT232R on the PCB appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port.
  • 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,
  • Fully assisted hardware (RTS#/CTS#) or X-On / X-Off software handshaking
  • Data transfer rates from 300 baud to 3 Mbaud at TTL levels
  • Internal EEPROM with user writeable area
  • PCB is USB Powered - no external supply required
  • Support for FT232R FTDIChip-ID™ feature for improved security
