The Arduino Nano V3.0 R3 (CH340G Version) is a compact and versatile microcontroller board based on the ATmega328P. It features the CH340G USB-to-serial converter, making it a cost-effective alternative to FTDI-based boards.

Designed for breadboard-friendly projects, the Nano provides the same functionality as Arduino Uno in a smaller form factor. It supports USB programming and can be powered via USB or external supply.

With multiple digital and analog I/O pins, PWM outputs, and communication interfaces (UART, I2C, SPI), this board is widely used in robotics, IoT, automation, and DIY electronics.

It is fully compatible with the Arduino IDE and supports a wide range of shields and modules.
