The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets.

Because of the separated pin plugs, this cable is ideal for powering and connecting up to the debug/login console on the Raspberry Pi or BeagleBone Black. Connect the pins as shown to power the Pi or BBB and establish the RX/TX link.

Also handy for hacking WiFi routers to install alternate OS's, or nearly any other 3.3V logic serial port. This is easier to use than an FTDI cable in many cases because the wires are separated. Note that Adafruit call this a "TTL cable" (since that's what they're called) but technically it's CMOS logic.

This cable is not good for Arduino re-programming such as a Boarduino, MENTA, Monochron, etc. because it does not have the DTR/RTS wire necessary for initiating the bootloader reboot sequence. For that we suggest an FTDI cable or FTDI friend.

Technical Details

There are four wires: red power, black ground, white RX into USB port, and green TX out of the USB port.
The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets.

Revision History

  • Prior to July 1 2014 this cable would come with a PL2303HX chipset and a black USB body. After July 1, 2014 Adafruit changed to a violet body and the PL2303TA chipset. The new 'TA cables are Win8 compatible, and are more reliable especially when dealing with random USB-disconnects.
  • As of Dec. 21, 2016 Adafruit will be shipping cables with SiLabs CP2012 chipset instead of Prolific. SiLabs chips seem to have better driver stability, and can handle very high speeds and 'unusual' non-standard baud rates. Other than the driver installation, the cables perform identically.

    Excellent product, I tested it on my Raspberry Pi 3 and it works with no issues. It's always good to have one of these. (Posted on 1/09/2017)

    This cable provides the best way to get information from your micro-controllers especially when you encounter a coding error. (Posted on 25/01/2016)

    The cable was easy to connect to the GPIO pins of the Pi. and allow one to have Serial connection with the Pi. able to send data to another computer using USB to Serial communications.

    The price is great as well, keep up the good work. (Posted on 10/03/2014)
