The Arduino Nano 3.0 with CH340 Chip is a compact and lightweight microcontroller board based on the ATmega328P. It is a smaller alternative to the Arduino Uno but offers similar functionality, making it perfect for projects with space constraints. The unsoldered version provides flexibility, allowing users to customize pin headers according to their requirements.
Unlike the original FTDI chip version, this Nano uses the CH340 USB-to-serial converter, ensuring cost efficiency while maintaining stable performance. It is fully compatible with the Arduino IDE and supports serial communication, analog inputs, PWM, and digital I/O, making it ideal for DIY electronics, robotics, IoT, and embedded projects.
