Also, Nano is breadboard friendly while Uno is not. UNO is twice as big as Nano and hence occupies more space on your project. One big difference between both is the size. 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.

Vin: Input voltage to Arduino when using an external power source (6-12V).ĥV: Regulated power supply used to power microcontroller and other components on the board.ģ.3V: 3.3V supply generated by on-board voltage regulator.

The Arduino Nano is another popular Arduino development board very much similar to the Arduino UNO.
