This board is using the chips atmega328p and ch340, Not ft232 as official arduino more breadboard space nano s got the breadboard, Ability of the boarduino and the mini usb with smaller footprint so users, Than either have more breadboard space. It s got a pin layout that works well with the mini or the basic stamp tx, Rx, Atn, Gnd on power and, One top ground alternatively. The nano can be powered via the mini, B usb connection, 7, 12v unregulated external power supply pin 30, Or 5v regulated external power supply pin 27 . The power source is automatically selected at the utmost level voltage source. It serves as a smallest, Complete, And breadboard friendly board. It has everything that diecimila/duemilanove has electrically with more analog input pins and onboard, 5v aref jumper.
