Arduino Nano Board R3 with CH340 chip W/O USB Cable (Unsoldered)

Arduino Nano Board R3 with CH340 chip W/O USB Cable (Unsoldered)


  • Description


The Arduino Nano Board R3 with  CH340 chipboard is based on famous Arduino platform and does all the functions of Arduino Uno, but with a smaller footprint. Arduino Nano Board R3 with  CH340 chip is vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good.

Arduino Nano Board R3 with CH340 has a lower cost USB-Serial Chip that makes it less in price than Arduino Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0). It has more or less the same functionality of the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.

Note:- CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.
