The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

All Arduino boards have this pin, and it's connected to the built-in voltage regulator that makes sure your board receives a stable supply. For the Nano, the VIN pin is found on Pin 30 (although ...
