Arduino Nano ESP32

The Nano ESP32 is a Nano-sized Arduino board based on the ESP32-S3. It can be programmed with both Arduino and MicroPython. It is aimed at those taking their first steps in IoT or MicroPython, as well as more experienced users who want to use it in their next project.

Key features

• Nano size: The board's small dimensions make it easy to integrate into standalone projects.
• Wi-Fi® and Bluetooth®: The ESP32-S3 microcontroller, well known in the IoT world, provides Wi-Fi and Bluetooth connectivity with full support from the Arduino environment.
• Arduino and MicroPython: You can switch from Arduino programming to MicroPython and back in a few simple steps. Arduino also offers an introductory course for those who have never worked with MicroPython. You will find more information on the documentation page.
• Arduino IoT Cloud compatibility: Build IoT projects with just a few lines of code. Security is handled by Arduino's setup process, and with the Arduino IoT Cloud app you can monitor and control your project from anywhere.
• HID support: The board can act as a human interface device over USB, for example as a keyboard or mouse. This lets you interact with your computer in new ways.

With the Nano ESP32 you have everything you need to start experimenting and creating with IoT and MicroPython.
