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

2.2 Processor
The Main Processor is a Cortex M4F running at up to 64MHz. Most of its pins are connected to the external
headers, however some are reserved for internal communication with the wireless module and the on-board
internal I2C peripherals (IMU and Crypto).
NOTE: As opposed to other Arduino Nano boards, pins A4 and A5 have an internal pull up and default to be used
as an I2C Bus so usage as analog inputs is not recommended.
2.3 Power Tree
The board can be powered via USB connector, VIN or VUSB pins on headers.
Power tree
NOTE: Since VUSB feeds VIN via a Schottky diode and a DC-DC regulator specified minimum input voltage is 4.5V the
minimum supply voltage from USB has to be increased to a voltage in the range between 4.8V to 4.96V depending
on the current being drawn.

3 Board Operation
3.1 Getting Started - IDE
If you want to program your Arduino Nano 33 BLE while offline you need to install the Arduino Desktop IDE [1] To
connect the Arduino Nano 33 BLE to your computer, you’ll need a Micro-B USB cable. This also provides power to
the board, as indicated by the LED.
3.2 Getting Started - Arduino Web Editor
All Arduino boards, including this one, work out-of-the-box on the Arduino Web Editor [2], by just installing a simple
plugin.
The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and support
for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board.
3.3 Getting Started - Arduino IoT Cloud
All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to Log, graph and analyze
sensor data, trigger events, and automate your home or business.
3.4 Sample Sketches
Sample sketches for the Arduino Nano 33 BLE can be found either in the “Examples” menu in the Arduino IDE or in
the “Documentation” section of the Arduino Pro website [4]
3.5 Online Resources
Now that you have gone through the basics of what you can do with the board you can explore the endless
possibilities it provides by checking exciting projects on ProjectHub [5], the Arduino Library Reference [6] and the
online store [7] where you will be able to complement your board with sensors, actuators and more

3.6 Board Recover
All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the
processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double-
tapping the reset button right after power up.
