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 it's I/O pins configured
to operate at 3.3V levels.
The TTL-232R-3V3-WE uses a 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 (3.3V), and GND signals. This allows the customer to customise the
TTL-232R-WE with their own connector, according to the requirements of their
application. Alternatively the TTL-232R-WE can be hard wired onto a PCB.
The TTL-232R-3V3-WE is fully RoHS compliant and is supplied loose packed in an
anti-static bag. It is FCC and CE approved.
IMPORTANT! You MUST use the 3V3 version of the cable. The radios interface will be damaged if 5V version (TTL-232R-5V-WE) is used!

Use the pin removal tool push from the front side into the slots and clear the complete connector.
At the FTDI cable you need attach contacts to four wires:
Black - Ground
Brown - CTS
Yellow - RXD
Orange - TXD
