FT232 3.3-5V TTL USB Serial Port Adapter with cable

You can call it the most reliable USB to serial converter that you can find!
Many operating systems support this standard chip. If it does not install automatically, then look for the driver for your operating system here .

Specifications:

• 3.3V and 5V TTL voltages (3.3V control signals and 5V compatible input signals)
• Converts TTL logic levels to computer RS232 levels
• Cable length: 100cm
• Red: +5V
• White: RX (3.3V-5V)
• Green: TX (3.3V, a 5V device would probably be compatible)
• Yellow or Brown: RTS (3.3V)
• Blue CTS (3.3V-5V)
• Black: GND (min)

For more information check the datasheet of the FT232RL.

Note: This cable gives 5V power, but the signals are 3.3V(output) or 3.3-5V(input) compatible! If your device is 3.3V, then you need to use a 5V to 3.3V voltage regulator in between for 3.3V power.
