1 The Board
As all Nano form factor boards, Nano 33 BLE does not have a battery charger but can be powered through USB or
headers.
NOTE: Arduino Nano 33 BLE 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
Sound spectrum: Create a sound spectrum to visualize sound frequencies. Connect an Arduino 33 Nano BLE and a
microphone or amplifier.
Social distancing sensor: Keeping the social distance has become more important than ever to ensure your own,
as well as others health. By connecting an Arduino Nano 33 BLE with a sensor and a LED display, you can create a
wearable band that alerts you when you get too close to other people.
Healthy plant scanner: Watering your plants isn’t always enough to keep them happy. Diseases, lack of sunlight
etc. could also be vital factors for unhealthy plants. Keep your plants happy by creating a detector and train it to
detect any diseases, all with an Arduino Nano 33 BLE
