The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

The Arduino Nano itself is the most basic and oldest of the group, and just like its many iterations, it's designed to work primarily with breadboards, making it a great tool for prototyping.

Features and Benefits. The Arduino Nano ESP32 presents a unique blend of features that make it the ideal microcontroller for an array of IoT applications, from home automation and gaming to education.
