Arduino Nano ESP32: Compact Power for IoT, MicroPython, and Beyond

The Arduino Nano ESP32 is a versatile and compact development board that introduces the powerful ESP32-S3 microcontroller to the Arduino ecosystem. Whether you're stepping into the world of IoT and MicroPython or you're an experienced developer building complex connected systems, this board is engineered to support your creativity and technical ambitions.

Compact Design, Big Capabilities

Designed with the classic Nano form factor, the Arduino Nano ESP32 measures just 45 mm in length and 18 mm in width, making it ideal for embedding into tight spaces, wearables, or portable devices. Its tiny footprint doesn't limit its capabilities-in fact, it's packed with the performance and connectivity features needed for modern embedded applications.

Wireless Connectivity: Wi-Fi and Bluetooth

At its core lies the u-blox NORA-W106 module, built around the ESP32-S3 chip. This microcontroller is renowned in the IoT community for its integrated Wi-Fi and Bluetooth Low Energy (BLE) capabilities. Whether you're creating a remote sensor, a smart appliance, or a wireless interface, the Nano ESP32 provides the connectivity to bring your ideas to life-untethered and in real-time.

Dual-Language Support: Arduino & MicroPython

One of the Nano ESP32's standout features is its native support for both Arduino and MicroPython. Beginners can start with Arduino's user-friendly environment, while more advanced users can take advantage of MicroPython's flexibility for scripting and rapid prototyping. Switching between languages is seamless, and Arduino provides an introductory MicroPython course to help newcomers get started quickly and confidently.

Arduino IoT Cloud Compatibility

Simplify your cloud-connected projects using the Arduino IoT Cloud, fully supported by the Nano ESP32. With just a few lines of code, you can build dashboards, monitor sensors, and control devices remotely. The platform handles security and infrastructure behind the scenes, so you can focus on functionality and design. (Support available from August 2023.)

USB HID Device Support

Thanks to its USB-C connector and built-in HID (Human Interface Device) support, the Nano ESP32 can emulate keyboards, mice, and other input devices. This opens up exciting possibilities for custom input systems, assistive technology, or even automation tools for PC interactions.
