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.

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.

Processor
The Main Processor is a Cortex M0+ running at up to 48MHz. 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. Communication with NINA W102 happens through a serial port and a SPI bus through the following pins.

WiFi/BT Communication Module
Nina W102 is based on ESP32 and is delivered with a pre-certified software stack from Arduino. Source code for the firmware is available [9].

NOTE: Reprogramming the wireless module’s firmware with a custom one will invalidate compliance with radio standards as certified by Arduino, hence this is not recommended unless the application is used in private laboratories far from other electronic equipment and people. Usage of custom firmware on radio modules is the sole responsibility of the user. Some of the module’s pins are connected to the external headers and can be directly driven by ESP32 provided SAMD21’s corresponding pins are aptly tri-stated. Below is a list of such signals:

rypto
The crypto chip in Arduino IoT boards is what makes the difference with other less secure boards as it provides a secure way to store secrets (such as certificates) and accelerates secure protocols while never exposing secrets in plain text. Source code for the Arduino Library that supports the Crypto is available [10]

IMU
The board has an embedded 6 axis IMU which can be used to measure board orientation (by checking the gravity acceleration vector orientation) or to measure shocks, vibration, acceleration and rotation speed. Source code for the Arduino Library that supports the IMU is available [11]

Board Operation

Getting Started – IDE
If you want to program your board while offline you need to install the Arduino Desktop IDE [1] To connect the Arduino 33 IoT to your computer, you’ll need a Micro-B USB cable. This also provides power to the board, as indicated by the LED.

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.

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.
Sample Sketches
Sample sketches for the Arduino 33 IoT can be found either in the “Examples” menu in the Arduino IDE or in the “Documentation” section of the Arduino Pro website [4]

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

Board Recovery
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.
