I recently bought some Arduino Nano clones. The clones are vastly cheaper, but they are clearly not as well made, and sometimes you might end up with slightly different versions of things. The official Arduinos also help fund the Arduino project, which is good for everyone.
If you are just getting started I would recommend getting a real one so you know it’s going to work and the documentation is correct.
Anyway, for my own documentation, these are the settings I needed to get it working:
Board: Arduino Nano
Processor: ATmega328P (Old Bootloader)
Built-in LED: 13
SDA: A4
SCL: A5
Here is the official pinout diagram for the Arduino Nano:
