This is an expansion module for use with the RP6V2 robot. The module enables you to upgrade your robot with an additional ATmega32 microcontroller and gives you an expansion board for interfacing with your own electronic circuits. Compared to the controller on the mainboard, this one features a twice-as-high clock frequency. As a bonus, on the RP6V2-M32 you will have a lot more free processing time because the motor control, ACS, IRCOMM, etc. can be handled by the controller on the mainboard.
