Arduino Nano Pinout Diagram Microcontroller Tutorials The arduino nano, as the name suggests is a compact, complete and bread board friendly microcontroller board. the nano board weighs around 7 grams with dimensions of 4.5 cms to 1.8 cms (l to b). this article discusses about the technical specs most importantly the pinout and functions of each and every pin in the arduino nano board. The arduino core already carries out a translation internally, so that pin designations (which you call pin numbers, labeled on the arduino board) are mapped to internal cpu port and port bit. the mapping changes between different arduino models, which is why you need a board definition file.
Arduino Nano Every Pinout Pdf The classic nano is the oldest member of the arduino nano family boards. it is similar to the arduino duemilanove but made for the use of a breadboard and has no dedicated power jack. successors of the classic nano are for example the nano 33 iot featuring a wifi module or the nano 33 ble sense featuring bluetooth® low energy and several environment sensors. Pin description. for pin description of arduino nano, let us assume some basic numbering. let the numbering begin with the tx pin (d1). so, tx is pin 1 rx is pin 2, rst is pin 3 and so on. on the other side, d13 is pin 16, 3v3 is pin 17 etc. with this information, let us now see the pin description of arduino nano. The pinout of the nano 33 iot is almost exactly the same as the original nano board (see diagram below). arduino nano 33 iot pinout. a couple of important things to remember are: the arduino nano 33 iot only supports 3.3 v for the gpio pins, so it is not 5 v tolerant like most of the other arduino boards. The arduino nano boasts 30 pins, 22 of which cater to input and output functions. among these, 14 digital io pins (d0 d13) can be customized using pinmode (), digitalwrite (), and digitalread () functions. capable of sourcing or sinking 40ma of current, these pins also feature internal pull up resistors, ranging from 20kΩ to 50kΩ.
