The Arduino Nano ESP32 is a development board that combines the popular Arduino Nano form factor with the capabilities of the ESP32-S3 microcontroller which is embedded in the NORA-W106-10B from u-blox®. This combination makes it a versatile tool for various projects, particularly those involving the Internet of Things (IoT).

The core of the board is the ESP32-S3 chip, known for its processing power and efficiency with Built-in Wi-Fi and Bluetooth LE (5.0) enable wireless communication, making it ideal for IoT applications.

The board can be powered through the USB-C port or an external voltage source (6 to 21V) and has a IO voltage of 3.3V with 40mA of soruce current and 28mA of sink current.

Nano ESP32 is compatible with Arduino Cloud platform and supports both Arduino IDE and MicroPython, providing flexibility for programmers from basic to advance.

Overall the Arduino Nano ESP32 seamlessly merges the user-friendly Arduino environment with the robust capabilities of ESP32 microcontrollers.
