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 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 create new ones) to be part of the IoT and design 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, which 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 on the WiFiNINA library reference page.

It is also possible to connect your board to different Cloud services, Arduino's own among others. 

Bluetooth® and Bluetooth® Low Energy

The communications chipset on the Nano 33 IoT can be both a Bluetooth® and Bluetooth® Low Energy client and the 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.

BEWARE: this kind of hacking breaks the certification of your WiFiNINA module, do it at your own risk.
