4. Module Pinout and Components
The Orangutan SVP contains a programmable AVR ATmega324PA or ATmega1284P microcontroller
connected to two motor drivers for direct control of two DC motors, a 16×2 character LCD, a buzzer,
three user pushbuttons, two user LEDs, and a demultiplexer for servo control. The AVR is also
connected to an auxiliary processor (a PIC18F14K50) that provides access to the battery voltage, a
10 kilo-ohm user trimmer potentiometer, and four additional input lines. The auxiliary processor also
serves as a programmer for the main processor, meaning that an external programmer is
not
required,
but you can use one if you want to. The auxiliary processor also allows for USB communication
between the AVR and a personal computer, and acts as a USB-to-serial converter.
