Description of the data exchange protocol between LPC2378 and COM-Express module over USB
Most of the I/Os comming with Robotino 3 are still connected to a NXP LPC2378 microcontroller (MC). In contrast to previous versions of Robotino the interface between the MC and Robotino's internal industral PC is no longer RS232 but USB. This page describes the protocol used for communication between MC and PC over USB.
