1 The Board

As all Nano form factor boards, Nano 33 IoT does not have a battery charger but can be powered through USB or
headers.
NOTE: Arduino Nano 33 IoT only supports 3.3V I/Os and is NOT 5V tolerant so please make sure you are not
directly connecting 5V signals to this board or it will be damaged. Also, as opposed to Arduino Nano boards that
support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB
power input.

1.1 Application Examples

Weather station: Using the Arduino Nano 33 IoT together with a sensor and a OLED display, we can create a small
weather station communicating temperature, humidity etc. directly to your phone.
Air quality monitor: Bad air quality may have serious effects on your health. By assembling the Nano 33 IoT, with
a sensor and monitor you can make sure that the air quality is kept in indoor-environments. By connecting the
hardware assembly to an IoT application/API, you will receive real time values.
Air drum: A quick and fun project is to create a small air drum. Connect your Nano 33 IoT and upload your sketch
from the Create Web Editor and start creating beats with your audio workstation of your choice.
