Options to power the Arduino Nano include USB, VIN, ... You can use a 6V to 20V unregulated external power supply, ... If you're adamant about using 5V to power your Nano, the 5V pin is the way to go.

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 uses a bootloader for handling programming the MCU, ... AVRs run from 1.8V to 5.5V, enough for unregulated 2 or 3 alkaline/NiMH cells or single Li-xxx cell.

Four new Nano boards join Arduino's lineup. Written by Liam Tung, Contributing Writer May 20, 2019 at 6:10 a.m. PT. ... (I/Os) and should not be used for connecting to 5V signals. ...

The most basic model in this lineup is the “Nano Every”, a 5V board with the ATmega4809 at its center. This brings 48 KB of flash and 6 KB of RAM to the party, running at 20 Mhz.

Power can be applied as 3.3V via pins, 5V via its USB-C connector or 6 – 21V via pins. Arduino has not included active power consumption on its data sheet but, according to the uBlox datasheet, module ...

The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance.
