Interface Cable

Description

For this project, the 25pin cargo bay connector on the iCreate was utilized. For a complete explanation of the pinout please see the iRobot Create Open Interface.

Note that the serial output from the ALIX 3D2 was attached to the side serial port on the Create with the iRobot supplied serial capable, which includes a level converter to shift the voltage levels to RS232, which is required by the ALIX board.
