I have an Arduino Duemilanove 2009. What I want is after I have programmed the ATMEGA328P-PU, I would like to remove it from the Duemilanove board and to use it alone with whatever component may needed (for example the crystal) in order to minimize as possible the circuit. Has anyone any schematic or PCB for ATMEGA328P-PU ?
I found on internet some but they were for other arduino microcontrollers.
Plus a 10K pull up resistor on the reset line and a 0.1uF capacitor across power and ground. Also recommended is is a 0.1uF cap from the Aref pin to ground, don't connect this pin to anything else.
