Nano V3.0 Mini USB ATmega328P-AU 5V CH340 Driver (Compatible with Arduino)

The Nano V3.0 (CH340) is a small, complete, and breadboard-friendly microcontroller board based on the ATmega328P. It is a highly popular, low-cost clone of the official Arduino Nano. The primary difference between this version and the official board is the USB-to-serial converter chip: instead of the standard FTDI FT232RL chip, it uses the CH340G chip. Because of this different chip, you will need to download and install the CH340 drivers on your computer (Windows/Mac) for the Arduino IDE to recognize the board. It functions exactly like an Arduino UNO but in a much smaller form factor, lacking only a DC power jack, and it works with a Mini-B USB cable instead of a standard one.
