The Arduino is basically just a processor chip on a breakout board that has some connectors, crystal, voltage regulator, USB interface.   The standard processor is an Atmel ATMEGA328.   The Arduino Nano is a shrunk down version that can be treated as a DIP packaged processor.  You can also buy bare ATMega328 chips with the Arduino bootloader pre-programmed.
