Overview

The Arduino Nano 33 IoT is a compact development board that combines the ARM Cortex-M0+ ATSAMD21G18A microcontroller with a u-blox NINA-W102 module for WiFi and Bluetooth connectivity. It features an integrated 6-axis IMU and an ATECC608A crypto chip, making it a secure and versatile platform for small-form-factor IoT applications.

Why Choose This Part

This board provides a seamless migration path for Arduino Nano users to 32-bit architecture and wireless connectivity while maintaining a compatible 18x45mm footprint. The combination of low-power ARM processing, hardware-level security, and a built-in IMU reduces the need for external components in complex IoT prototypes.

Applications

IoT Sensor Node
Utilize the 8 analog inputs and onboard WiFi to collect and transmit sensor data to cloud services like Arduino Cloud or AWS.
Secure Edge Devices
Leverage the hardware-based ATECC608A crypto chip to manage secure connections and store certificates for encrypted IoT communication.
Basic Robotics and Motion Tracking
The integrated 6-axis IMU allows for orientation and motion detection in compact robotics projects without external breakout boards.
Smart Home Gateway
Acts as a bridge between local Bluetooth Low Energy (BLE) peripherals and a home WiFi network for remote automation.

Getting Started

Program the board using the Arduino IDE or Web Editor by installing the Arduino SAMD Boards core. Note that the board operates at 3.3V logic; applying 5V to any I/O pin will damage the ATSAMD21G18A microcontroller. For secure applications, use the ArduinoECCX08 library to interface with the onboard crypto chip.
