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

The Arduino Nano itself is the most basic and oldest of the group, and just like its many iterations, ... Speaking of power pins, the Nano can also use its 5V pin as an input.

While the pinout is very similar to the Arduino Nano’s, there are four (12-bit) analogue inputs rather than eight (10-bit). Some digital GPIO pins are numbered differently too.

With its precision, flexibility, and power, the Nano 33 BLE Rev2 is poised to redefine what’s possible in the world of electronics. Exploring the Arduino Nano 33 BLE Rev2’s Advanced Features ...

The 32U4 in arduino-land can sometimes be a bit problematic with regards to firmware updating and reset issues, “brickable” as it were. The Nano footprint is quite nice (similar in size to a ...

You have to pull an extra wire from the sensor’s input voltage to your Arduino’s AREF pin, so you know what the actual voltage at the end of the cable is, so you can estimate the 10-90% range.
