Options to power the Arduino Nano include USB, VIN, and 5 volt pin, meaning you have power options for almost any situation.

The new Arduino Nano designs bring a lot of power to a small footprint. I have to wonder if Arduino is looking to compete with ESP32 modules.

Available to purchase for £8 or $8 depending on your location the Maker Nano RP2040, as the name suggests, features a Arduino Nano form factor and is powered by a Raspberry Pi RP2040.
