The new member of our iconic Arduino Nano family, the Nano ESP32. This board brings all the power of the well-known ESP32-S3 with the full support of the Arduino ecosystem, allowing makers to explore the world of Arduino and MicroPython without any blocker. Just unleash your creativity and start building for the next IoT project.
Whether you're a beginner stepping into the world of IoT or MicroPython, or an advanced user looking to incorporate it into your next product, the Nano ESP32 is the perfect choice. It covers all your needs to kick-start your IoT or MicroPython project with ease.
The Arduino Nano ESP32 is the first-ever Arduino board based on a ESP32 microcontroller from Espressif, the NORA-W106 module from u-blox®. This module supports both Wi-Fi® and Bluetooth® (5.0 and above), making it an ideal device for IoT development. The popular Nano form factor also makes it compatible with many hardware accessories.
With a USB-C connector, 16 MB (128 Mbit) of Flash and support for MicroPython & Arduino IoT Cloud enabled - it is a very versatile development board.
This board is a perfect entry point to learn MicroPython, dive into it with our free course: MicroPython 101
- Tiny footprint: Designed with the well-known Nano form factor in mind, this board's compact size makes it perfect for embedding in standalone projects.
- Wi-Fi® and Bluetooth®: Harness the power of the ESP32-S3 microcontroller, well-known in the IoT realm, with full Arduino support for wireless and Bluetooth® connectivity.

Is the Nano ESP32 compatible with MicroPython?
Absolutely! This board fully supports MicroPython. For detailed information on setting it up and getting started with MicroPython, please visit docs.arduino.cc/nano-esp32.
How can I power the Nano ESP32?
The Nano ESP32 can be powered in two ways. Firstly, you can power it via the USB port, which activates the VBUS pin as an output. Alternatively, you can supply power through the VIN pin, accepting an input voltage range of 5 to 18 Volts.
Does it use the official ESP32 core?
Yes, if you are an ESP32 user, simply install the latest version of the Arduino Nano ESP32 core through the board manager in the Arduino IDE. For more information, please refer to the official documentation page.
Will the Nano ESP32 be compatible with sketches from generic ESP32 boards?
The Arduino Nano ESP32 can run code written for other ESP32 devices without any fuss. It's designed to be fully compatible with the ESP32 ecosystem, making it easy to port existing code.
