Arduino Nano V3.0 Card is 100% compatible with the Nano card and fully compatible with Windows, Mac, and Linux operating systems. It is based on the famous Arduino platform and does all the functions of Uno, but with a smaller footprint. The Nano can be powered via the mini-USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

The Nano Board R3 with CH340 chip without USB Cable 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. This Nano equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.

The CH340 chip Nano Arduino Kit is a small, complete, and breadboard-friendly board based on the ATmega328 (Nano R3). It has more or less the same functionality as the Uno 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. The size of Nano V3.0 with CH340 Chip is only 43 mm x 18 mm; it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed, and 32kB of flash memory.

  • CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.
  • This board comes with OLD BOOTLOADER buy it accordingly

Works as advertised

Works perfectly. I built OttoDIY the robot with it, works great.I plan to buy this product again for other projects.

Nice Robust Hard to Kill Board!

I was thinking whether I should get the genuine Nano board or get a knock-off for my first ever Arduino project, but I am glad I finally went with this one. I even fried the board in the first 15 minutes by enabling HIGH on an input pin and smoke came out of this little thing. I thought I had to order a new one, but when I looked at the back, I saw that one of the capacitors near the USB port was fried, so I just shorted the pins with my soldering iron, and bam, the board came back online fully functional!!! It's totally worth the money, and I am so glad I didn't pay the hefty price for the original board. Next step for me is to either get some PCB or the Terminal IO Shield.

It works great but you need to download a driver because it uses a different serial programmer chip

 Great little arduino nano clone 😀 works just as well as the official nano

Good enough

Mini Nano is Really Small and Really Functional

You might want to try this for your next Arduino project. It has most of the functionality of an Uno board in a fraction of the size.


It was good.

bhola sarkar
size matters! smaller the better.

I have purchased 7 uno's and one mega! But this nano is 1/3 the size and just as useful as a uno!

dinesh singh rana
Very handy

Very handy Arduino for quick project.

Great Value

This is the cheapest option for just one of these that I could find. I purchased this to replace an old nano that had broken on my DIY CNC lasercutter. I was able to lead all the hex files I needed onto it using x-loader and had it up in running in 5 minutes.

Works, but have to use the old bootloader in Arduino IDE

Uploaded the blink sketch, but have yet to check the pins.
