The Board

Like 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.

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 training it to detect any diseases, all with an Arduino Nano 33 BLE

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 used as analog inputs is not recommended.

Power Tree

The board can be powered via the USB connector, VIN, or VUSB pins on headers.

Pinouts1 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.

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.
