1 The Board
As all Nano form factor boards, Nano 33 IoT and Nano 33 IoT with headers does not have a battery charger but can
be powered through USB or headers.
NOTE: Arduino Nano 33 IoT and Nano 33 IoT with headers 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 or Nano 33 IoT with headers 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 board, 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 board and upload your sketch from
the Create Web Editor and start creating beats with your audio workstation of your choice.
