Arduino Nano 33 IoT is a small, robust and powerful board with Wi-Fi and Bluetooth connectivity that is a practical and cost-effective solution thanks to its low-power architecture. It is fully compatible with the Arduino IoT Cloud and supports secure TLS transport. The ATECC608A cryptochip stores the cryptographic keys in hardware, providing a very high level of security for this product class. The integration with the Arduino IoT Cloud also provides a very efficient way to set up online dashboards with little programming and minimal effort. It is the easiest and most cost-effective entry point to enhance existing devices (and create new ones) to become part of the IoT and develop pico-network applications. Wi-Fi and Bluetooth connectivity is provided by a module from u-box, the NINA-W10, a low-power chipset that operates in the 2.4 GHz range. It is perfect for simple vibration alarm systems, pedometers and the relative positioning of robots.
