Arduino Nano 33 IoT Development Board with Headers

The Arduino Nano 33 IoT Development Board with Headers is a compact development board built around a 32-bit Arm Cortex-M0+ processor, with integrated Wi-Fi and Bluetooth connectivity for Internet of Things projects.

Overview

Wi-Fi and Bluetooth connectivity is provided by an ESP32-based module, giving a direct route into IoT development. The ultra-low-power Arm Cortex-M0+ processor supports the design of connected devices. The board is fully compatible with the Arduino IoT Cloud, which allows online dashboards to be created and devices to be managed with minimal coding effort.

Key Features

• Built-in 6-axis IMU (inertial measurement unit) for motion sensing
• Dedicated crypto chip acting as a secure element for storing certificates and pre-shared keys
• Support for TLS secure transport of data
• Pin headers pre-soldered for breadboard prototyping
• Castellated pads for surface-mounting (SMT) onto a custom PCB

Installation Options

The pre-soldered pin headers allow the board to be used directly on a breadboard for rapid prototyping. Alternatively, the castellated pads allow it to be surface-mounted onto a custom PCB, making it an embedded module for final product designs.

Applications

The board is particularly suited to pico-networks, wearable technology, remote sensors, and smart home devices. Its small Nano form factor makes it suitable for space-constrained applications, and it serves as an entry point for adding IoT capabilities to existing devices or creating new networked applications.

Specifications

• Processor: 32-bit Arm Cortex-M0+ (SAMD21G18A)
• Connectivity: Wi-Fi
• Width: 3.3
• Depth: 1.5
• Height: 4.3
• Weight: 18 g

Important Usage Note

The Arduino Nano 33 IoT operates exclusively at 3.3V, and its I/O pins are NOT 5V tolerant. Connecting 5V signals directly to the board will cause permanent damage.
