Description
Arduino Nano CH340 USB Development Board (Without USB Cable)
This version uses the CH340 USB-to-Serial converter, which significantly reduces cost compared to older Nano boards that used the FTDI chip, while maintaining full programming and serial communication support.
The Nano can be powered via the Mini-B USB port, an external unregulated supply (7–12V), or a regulated 5V power source. The board automatically selects the highest available voltage source.
Key Features

Customer Reviews
Works perfectly. I built OttoDIY the robot with it, works great.I plan to buy this product again for other projects.
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.
Great little arduino nano clone 😀 works just as well as the official nano
Good enough
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.
I have purchased 7 uno's and one mega! But this nano is 1/3 the size and just as useful as a uno!
Very handy Arduino for quick project.
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.
Uploaded the blink sketch, but have yet to check the pins.
