I see from the drawing that there are some I/O pins available on J8. Does anyone know how they are mapped with regard to Arduino compatibility? I see PC0-PC3,ADC6,ADC7,PD2 and PD3 are available and mapped to the ATmega’s pins. I was hoping someone knew the corresponding I/O pin numbers in the Arduino. I need at least one analog (ADC) and one digital pin.
