The TTL-232R-3V3-WE ("wire ended") is a USB-to-Serial (TTL level) converter cable which allows for a simple way to connect TTL interface devices to USB. This version of FTDI's USB to TTL serial adapter cable has its I/O pins configured to operate at 3.3V levels.
This USB-to-serial cable uses an FT232RQ device which is housed inside the USB 'A' connector, and is terminated at the end of a 1.8 m (70") cable with 6 bare, tinned wires which provide access to transmit (Tx), receive (Rx), RTS#, CTS#, Vcc (5V), and GND signals. This allows you to customize the USB-to-serial cable with your own connector, according to the requirements of your application. Alternatively the USB-to-serial cable can be hard-wired onto a PCB.
The TTL-232R-3V3-WE is fully RoHS compliant and is FCC and CE approved.
