Arduino NANO CH340

Arduino NANO CH340

The Arduino Nano CH340 is a compact and breadboard-friendly microcontroller board based on the ATmega328P. It offers the same functionality as the standard Arduino Nano but uses the CH340 USB-to-Serial converter chip instead of the FTDI chip, making it more affordable while maintaining full compatibility with the Arduino IDE.
