This has a counterfeit FTDI chip. The FTDI chip on the board is what allows you to program the arduino via USB. The latest Windows update, or current driver version from FTDI disables the device permanently. I did not know I was purchasing a device with a fake FTDI chip. The new driver update disabling these devices has been in the news (forums) the last few weeks since the October Windows update.
Looking at the chip it says "FTDI", but there are subtle differences between the fake chip on the board and a real chip I have on another board. Do not buy an Arduino unless it is from a known reputable source. FTDI has recommendations about which brands use legitimate FTDI chips.
Before plugging anything in I went to the first website below. That led me to the FTDI website that was listed earlier in other peoples posts.
Next I navigated to Device Settings and connected devices, not the manager or anything else.
If you did the proper set up for Win 10 and changed your update settings and other security fixes, you have to undo only one of them here.
Allow downloads for metered connections.
Plug in the NANO to your USB and if it doesn't pop up right away scan for a new device or add a new device.
I then installed the Arduino software and unchecked the box marked drivers.
Run the blink or another basic example and see if it works for you.
If you had any steps I missed add a comment please.
I hope it works for you as well.
Might I also add that it was very poorly packaged, as several of the header pins were severely bent.
Update: Vendor contacted me today apologizing for the problems and offering to fix it. I still plan to send it back and get a different board, but I was pleased with the seller's attempts to make amends. I can only assume that they would make it right, but since i am not giving them an opportunity to, I am changing my review to 3 stars (from 1) for customer service. Still frustrated, but at least they tried to make it right.
I did not know about other choices and bought it. It is partly my fault.
Anyway, I hope this information would help you to decide on your purchase if you are in the same situation as mime.
I am using it with Raspberry pi. It works sometimes, but not all the time. It worked perfectly with PC. With Raspberry Pi, USB is detected by Pi only if nano is powered by USB port from Raspberry pi. It does not work if Arduino Nano is connected to an external power source.
My solution is to get an Arduino nano with CH340G chip. That works perfectly with my PC and Raspberry Pi. This product does not work for my application.
