Arduino Nano – Complete Technical Overview

The Arduino Nano is a compact microcontroller board based on the ATmega328P. It offers the same functionality as the Arduino Uno but in a smaller, breadboard-friendly format.

 Why Choose Arduino Nano?

  • Small size (45mm x 18mm)
  • Breadboard compatible
  • Lower cost than Uno
  • Perfect for embedded projects

⚙️ Technical Specifications

  • Microcontroller: ATmega328P
  • Operating Voltage: 5V
  • Input Voltage: 7–12V
  • Digital I/O Pins: 14 (6 PWM)
  • Analog Inputs: 8
  • Flash Memory: 32KB
  • Clock Speed: 16 MHz

 CH340 vs FT232 – What’s the Difference?

FT232 Version

  • Original USB-to-Serial chip
  • Stable drivers
  • Higher cost

CH340 Version

  • Most common clone version
  • Lower price
  • Requires manual driver installation (sometimes)

Arduino Nano vs Arduino Uno

  • Nano is smaller and breadboard-friendly
  • Uno has standard shield support
  • Nano is better for compact projects
