Arduino Nano 33 IoT, SAMD21G18A, with header

Arduino Nano 33 IoT - small, secure and with WLAN based on the SAMD21G18A microcontroller.
This small, rugged and powerful board features WiFi and Bluetooth connectivity, combined with its low-power design, makes it a convenient and cost-effective solution for your networked projects.



The Arduino Nano 33 IoT is fully compatible with the Arduino IoT Cloud. The ATECC608A cryptochip stores the cryptographic keys of the hardware and provides a very high level of security for this product class. Integration with the Arduino IoT Cloud gives you the ability to set up online dashboards with minimal programming and effort.

In the same iconic size as the Arduino Nano, the Arduino Nano 33 IoT houses an Arm Cortex-M0+ SAMD21 processor, an ESP32-based WiFi and Bluetooth module, a 6-axis inertial measurement unit (IMU), and a crypto chip that can securely store certificates and pre-approved keys.

It can be used in a hole grid board when mounted with pin strips or as SMD directly on a printed circuit board.
