Arduino Nano 33 IoT

Overview

The Arduino Nano 33 IoT is a compact development board that combines an ARM Cortex-M0+ microcontroller with WiFi and Bluetooth connectivity. It features a built-in 6-axis IMU and a dedicated ECC608A crypto chip to handle hardware-based security for IoT applications.

Why Choose This Part

This board provides a seamless upgrade path from 8-bit AVR boards by offering 256KB of Flash and 32KB of RAM in a breadboard-compatible footprint. It simplifies secure cloud integration through its dedicated hardware security module and supports both WiFi and Bluetooth Low Energy (BLE) without requiring external shields.

Applications

Getting Started

Program the board using the Arduino IDE or Arduino Cloud by selecting the Arduino Nano 33 IoT board definition. Ensure you have the WiFiNINA and Arduino_LSM6DS3 libraries installed to access the wireless and IMU features. Note that the board operates at 3.3V and the IO pins are not 5V tolerant.

Also Consider
