The Arduino Nano V3.0 with Cable is a compact, breadboard-friendly version of the Arduino board, widely used for DIY electronics, robotics, and embedded projects. It has the same functionality as the Arduino UNO but in a much smaller form factor, making it ideal for projects where space is limited. The package usually comes with a USB cable (Mini-USB or Micro-USB, depending on the version) to connect the board to a computer for programming and power supply. 🔹 Key Features of Arduino Nano V3.0: Microcontroller: ATmega328P (same as Arduino UNO). Operating Voltage: 5V. Input Voltage (Vin): 7–12V (when using external power). Digital I/O Pins: 14 (6 of which can be used as PWM outputs). Analog Input Pins: 8. Flash Memory: 32 KB (of which 2 KB used by bootloader). SRAM: 2 KB. EEPROM: 1 KB. Clock Speed: 16 MHz. USB Connection: Mini-USB (older models) or Micro-USB (clones/upgraded models). Dimensions: ~45mm x 18mm (much smaller than UNO). 🔹 Advantages: Small size – fits easily on a breadboard. Same functionality as Arduino UNO but cheaper. Can be powered via USB cable or external adapter/battery. Useful for permanent installations or embedded projects. 🔹 Using Arduino Nano V3.0: Connect the USB cable (Mini-USB or Micro-USB) to your computer. Install the Arduino IDE on your PC (if not already installed). In the IDE, go to Tools → Board → Arduino Nano and select the correct Processor (ATmega328P). Select the correct COM port under Tools → Port. Upload your code – the Nano will run just like an UNO. If needed, supply external power through Vin pin (7–12V) or 5V pin for direct regulated power. 🔹 Applications: Mini robotics projects (cars, drones, automation). Sensor-based projects (IoT, weather stations, home automation). Wearable electronics (due to its small size). Educational projects (cost-effective compared to UNO).
