This cable is a USB to Serial (TTL level) converter cable. It’s identical functionally to the FTDI Cable. It’s one of the easiest ways to connect a TTL interface device to USB. and fits directly to many boards including the Lilypad mainboard.
The cable uses FTDI’s FT232R chip, which is powerful and well documented. The device is housed inside the USB ‘A’ connector and is terminated at the end of a 1.8-meter cable (6 foot) with a 0.1″ pitch header socket which provided access to transmit (Tx), receive (Rx), RTS# and CTS#. These lines all operate at 3.3V levels. Also brought out in the header are VCC (5V) and GND.
TTL-232R Converter Cable provides a USB to TTL Serial interface with various end connectors.
On board, FT232RL 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.
UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space /no parity.
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 the user-writable area.
5V CMOS drive outputs and 5V safe TTL inputs make the TTL-232R easy to interface to 5V MCU‟s.
FTDI‟s royalty-free VCP allow for communication as a standard emulated COMport and D2XX „direct‟ drivers provide DLL application programming interface.
Support for FT232R FTDIChip-ID™ feature for improved security.
+5V or +3.3V output allows external logic to be powered from the USB port.
6-way outputs provide Tx, Rx, RTS#, CTS#, VCC and GND (except Audio Jack which provides only TX, RX and GND).
8 way, keyed connector to support FTDI VDRIVE2 and VMUSIC2.
3-way Audio Jack connector provides Tx, Rx and GND.
