Introducing the Nano ESP32, a powerful addition to the Arduino ecosystem that brings the popular ESP32-S3 to the world of Arduino and MicroPython programming. 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.

Nano ESP32 is a 3.3 V development board based on the NORA-W106-10B from u-blox®, a module that includes a ESP32-S3 system on a chip (SoC). This module has support for Wi-Fi® and Bluetooth® Low Energy (LE), with amplified communication through a built-in antenna. The CPU (32-bit Xtensa® LX7) supports clock frequencies at up to 240 MHz.
