The Console lead has four female connections that can be plugged directly onto the GPIO header of the Raspberry Pi. The Adafruit USB console cable has 3.3V logic, so its safe to use with your Pi. | The Console lead has four female connections that can be plugged directly onto the GPIO header of the Raspberry Pi.

For this experiment, the serial lead is going to power the Raspberry Pi. So, DO NOT attach the Pi's USB power adapter.
