If for any reason there is no Voltage label on the cable, then the above pictures show you how to identify them. The plastic inside the connector housing will be black for 3.3 Volts, and white for 5 Volts.

You can also test the voltage by plugging the unit into a USB port and measuring the voltage between Ground and any data pin.

Need a TTL-232R-5V-WE or a TTL-232R-3V3-WE cable? All Audio Jack type cables have 6 colour coded wires inside, so all you need to do is cut the AJ connector off, and strip the sheathing back to the required length.
