20+ Arduino Nano Every Pin Numbers Background. Is there more information about the nano every out there? One big difference between both is the size uno is twice as big as nano and hence occupies more space on your project.
The arduino nano has a number of facilities for communicating with a computer, another arduino, or other microcontrollers.
Arduino nano has similar functionalities as arduino duemilanove but with a different package. Both arduino uno and arduino nano come with same functionality with little difference in terms of pcb layout, size and form factor. One big difference between both is the size uno is twice as big as nano and hence occupies more space on your project. Here there's a detailed image of one arduino nano.
