This robot controller is by far the most powerful Orangutan, and it is intended for small and medium-sized robots. The design features a dual-AVR architecture that leaves an ATmega1284P AVR microcontroller almost completely available to the user while taking care of low-level motor control tasks on a pre-programmed mega328, which also doubles as a programmer for the master processor. This version features VNH3SP30 motor drivers and a 4-line x 20-character LCD.
