Download Arduino Nano V3 Pinout Pdf Images. The arduino nano 33 iot only supports 3.3v for inputs and outputs (io pins) and it is not 5v tolerant like most of the other arduino boards. If you want the reference voltage to be 0v to 3.3v, we can give 3.3v to aref pin (18th pin) by.
We've created a well explained, diagram by default, the pins are measured from ground to 5v.
In this guide, learn about arduino nano pin outs and diagrams. The arduino nano 33 iot only supports 3.3v for inputs and outputs (io pins) and it is not 5v tolerant like most of the other arduino boards. The 3.3v pin is also powered from the ft232r voltage regulator that supports up to 50ma. Arduino pc6(reset) pb6cxtal1) pb7cxtal2) pdocrxd) pd1.
