Arduino Nano 33 IoT (with Headers)

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 BLE 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

Arduino has 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

• 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

• 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 BLE

The communications chipset on the Nano 33 IoT can be both a BLE and Bluetooth® 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
