This 80cm cable is the easiest way ever to connect to your Raspberry Pi or microcontroller. Inside the USB plug is a USB to Serial conversion chip and at the end of the cable 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

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.

Please note: This cable is not suitable for reprogramming Arduino based devices please use an FTDI based cable/device for this.


  • Red: Positive Power
