Arduino Mega is more powerful than an Arduino Nano in terms of speed and number of I/O pins. There is a considerable amount of difference between the Arduino Nano and the Arduino mega as the processor used itself is different. Nameĭifference between Arduino Nano and Arduino Mega The technical difference between Uno and Nano is shown below. To program a Uno you need Regular USB cable where as for Nano you will need a mini USB cable. Also Nano is breadboard friendly while Uno is not. One big difference between both is the size UNO is twice as big as Nano and hence occupies more space on your project. They use the same Processor (Atmega328p) and hence they both can share the same program. The Arduino Nano is very much similar to the Arduino UNO.
