Hi there
Im trying to connect a sensor to my arduino due. I want to change the refrence voltage to 2.5 volt.
It will work with analogReference(External) then I connect my 2.5 to the SUE board. But I couldnt fint any indication which Pin I should connect my external voltge to
Thansk in Advance
It is AREV
Caution !!
he AREF pin is connected to the SAM3X analog reference pin through a resistor bridge. To use the AREF pin, resistor BR1 must be desoldered from the PCB.
