15+ Arduino Nano Pinout Isp Images. One big difference between both is the size uno is twice as big as nano and hence occupies more space on your project. Please note that the mkr family of boards share the same pinout, therefore you can use any mkr board as isp programmer.

The arduino nano is very much similar to the arduino uno. We will see all the pins section wise we can use one arduino to program another arduino using this icsp. Each pin on the nano board comes with a specific function associated with it.

They use the same processor (atmega328p) and hence they both can share the same program.
