The TTL-234X-3V3 is a USB to Serial (TTL level) converter cable which allows for a simple way to connect TTL interface units to USB. This version of FTDI's USB to TTL serial adapter cables has it's I/O pins configured to operate at 3.3V levels.
The TTL-234X-3V3 uses a FT234X IC which is housed inside the USB 'A' connector, and is terminated at the end of a 1.8 meter cable 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 on the header are Vcc (5V), and GND.
The TTL-234X-3V3 is fully RoHS compliant and is supplied loose - packed in an anti-static bag. It is FCC, CE approved.
