The other difference between Arduino Nano board and Arduino Mini board is support of in-built connectors.The size of Arduino board is much smaller than Arduino Nano board. It is mainly because of small size of The Arduino Mini board. The Arduino Mini board has greater compatibility compared to Arduino Nano board. When the Arduino boards design the main factor that need to be considered as compatibility with other device. The another difference between two board is the compatibility factor.While on other hand, there is no in-built support of USB port in Arduino Mini board and the board need to use external USB adapter to connect other devices to the board. In the Arduino Nano board there is one mini USB port fit in it and can use to provide power supply to the board. The other difference between Arduino Nano board and Arduino Mini board that can be considered is support of the USB jack in board.When there is requirement of selecting the board for small projects the Arduino Mini board prefers over Arduino Nano board as the size of Arduino Mini board is smaller compare to Arduino Nano board. The one of the major differences between Arduino Nano board and Arduino Mini board that can be considered is the use of the board.Let us discuss some of the major key differences between Arduino Nano and Mini: Key Difference Between Arduino Nano vs Mini Hadoop, Data Science, Statistics & others
