Arduino Nano Development Board – Compact ATmega328P Microcontroller

The Arduino Nano is a compact, breadboard-friendly microcontroller board built around the ATmega328P. It packs the same processing power as the Arduino Uno into a form factor roughly half its size — making it ideal for wearables, sensor nodes, robotics, and any project where space is limited.

Key Features

• ATmega328P microcontroller — same core as Arduino Uno
• 8 analog inputs (A0–A7) vs 6 on the Uno — more sensor channels
• Mini USB connector for programming and power
• CH340 USB-to-serial chip (install CH340 driver on Windows)
• Directly plugs into a standard breadboard for rapid prototyping
• Fully compatible with Arduino IDE and all Arduino libraries
• On-board power LED, TX/RX indicator LEDs, and reset button

Applications

• Wearable electronics and compact sensor nodes
• Robotics and motor driver control
• IoT data logging and wireless projects (with ESP module)
• Automation and relay switching circuits
• Final year and college engineering project kits

Getting Started

Plug in via Mini USB, install the CH340 driver if on Windows, then select Arduino Nano (ATmega328P) in the Arduino IDE. Use Old Bootloader as the processor option if uploads fail. Pair it with a DHT11 sensor and jumper wires to build your first temperature monitoring project in minutes.
