Description
Arduino Nano 33 IoT allows you to build your next smart project. Ever wanted an automated house? Or a smart garden? Well, now it’s easy with the Arduino IoT Cloud compatible boards. It means: you can connect devices, visualize data, control and share your projects from anywhere in the world. Whether you’re a beginner or a pro, we have a wide range of plans to make sure you get the features you need.
The Arduino Nano 33 IoT is the easiest and cheapest point of entry to enhance existing devices (and creating new ones) to be part of the IoT and designing pico-network applications. Whether you are looking at building a sensor network connected to your office or home router, or if you want to create a Bluetooth® Low Energy device sending data to a cellphone, the Nano 33 IoT is your one-stop-solution for many of the basic IoT application scenarios.
The board’s main processor is a low power Arm® Cortex®-M0 32-bit SAMD21. The WiFi and Bluetooth® connectivity is performed with a module from u-blox, the NINA-W10, a low power chipset operating in the 2.4GHz range. On top of those, secure communication is ensured through the Microchip® ECC608 crypto chip. Besides that, you can find a 6 axis IMU, what makes this board perfect for simple vibration alarm systems, pedometers, relative positioning of robots, etc.
WiFi and Arduino IoT Cloud
At Arduino we have made connecting to a WiFi network as easy as getting an LED to blink. You can get your board to connect to any kind of existing WiFi network, or use it to create your own Arduino Access Point. The specific set of examples we provide for the Nano 33 IoT can be consulted at the WiFiNINA library reference page.
It is also possible to connect your board to different Cloud services, Arduino’s own among others. Here some examples on how to get the Arduino boards to connect to:
- Arduino’s own IoT Cloud: Arduino’s IoT Cloud is a simple and fast way to ensure secure communication for all of your connected Things. Check it out here
- Blynk: a simple project from our community connecting to Blynk to operate your board from a phone with little code
- IFTTT: see an in-depth case of building a smart plug connected to IFTTT
- AWS IoT Core: we made this example on how to connect to Amazon Web Services
- Azure: visit this github repository explaining how to connect a temperature sensor to Azure’s Cloud
- Firebase: you want to connect to Google’s Firebase, this Arduino library will show you how
Note: while most of the above-shown examples are running on the MKR WiFi 1010, both boards have the same processor and wireless chipset, which means it will be possible to replicate them with the Nano 33 IoT.
Bluetooth® and Bluetooth® Low Energy
The communications chipset on the Nano 33 IoT can be both a Bluetooth® and Bluetooth® Low Energy client and host device. Something pretty unique in the world of microcontroller platforms. If you want to see how easy it is to create a Bluetooth® central or a peripheral device, explore the examples at our ArduinoBLE library.
We Make it Open for you to Hack Along
The Nano 33 IoT is a dual processor device that invites for experimentation. Hacking the WiFiNINA module allows you to, for example, make use of both WiFi and Bluetooth® and Bluetooth® Low Energy at once on the board. Yet another possibility is having a super-lightweight version of linux running on the module, while the main microcontroller controls low level devices like motors, or screens. These experimental techniques, require advanced hacking on your side. They are possible via modifying the module’s firmware that you can find at our github repositories.
BEWARE: this kind of hacking breaks the certification of your WiFiNINA module, do it at your own risk.
Specifications
Here you will find the technical specifications for the Arduino® Nano 33 IoT.
Please read: operating voltage
The microcontroller on the Arduino Nano 33 IoT runs at 3.3V, which means that you must never apply more than 3.3V to its Digital and Analog pins. Care must be taken when connecting sensors and actuators to assure that this limit of 3.3V is never exceeded. Connecting higher voltage signals, like the 5V commonly used with the other Arduino boards, will damage the Arduino Nano 33 IoT.
To avoid such risk with existing projects, where you should be able to pull out a Nano and replace it with the new Nano 33 IoT, we have the 5V pin on the header, positioned between RST and A7 that is not connected as default factory setting. This means that if you have a design that takes 5V from that pin, it won’t work immediately, as a precaution we put in place to draw your attention to the 3.3V compliance on digital and analog inputs.
5V on that pin is available only when two conditions are met: you make a solder bridge on the two pads marked as VUSB and you power the NANO 33 IoT through the USB port. If you power the board from the VIN pin, you won’t get any regulated 5V and therefore even if you do the solder bridge, nothing will come out of that 5V pin. The 3.3V, on the other hand, is always available and supports enough current to drive your sensors. Please make your designs so that sensors and actuators are driven with 3.3V and work with 3.3V digital IO levels. 5V is now an option for many modules and 3.3V is becoming the standard voltage for electronic ICs.

Getting Started
The Getting Started section contains all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.
Upload you first sketch code
Here are steps to connect you Nano 33 IoT board.
Step 1: Go to Tools>>Board>>Board Manager: install “Arduino SAMD Board”

There are also other libraries need for specific functions:
- WiFiNINA: for enabling network connections
- Arduino LSM6DS3: for reading accelerometer and gyroscope values
- Arduino RTCZero: for reading realtime clock
- ArduinoBLE: for bluetooth
Step 3: Select board and port
Step 4: Get the code (here we use ScanNetowrk as sample code to scan nearby wireless networks) and upload the scketch
Step 6: Open you Serial Monitor to read data (in our case, we have scanned wifi networks including ours “FARANUX-ELECTRONICS-CBFB”)
Now you are good to go. Start Internet Of Thing with Nano 33 IoT board. Use bluetooth, Wifi, and so on.
