Arduino Nano board

Jay,

On the Arduino software, make sure that you are configuring the loader for the NANO (where you select the board type). This has happened to me many times

What are you trying to do with the Nano?

Bryce

I agree with Bryce, other than telling the loader you're using the Nano, it should be simple.  Note that many of the Chinese knockoffs of the Arduino boards won't necessarily be recognized by the Arduino software, that's not the fault of the Arduino.

Jay,

Good advice from Bryce, check that you have "Nano" board selected in the Arduino IDE program.  I run Nano's on my layout to control accessories and something that I find helpful is do the development programing on a Nano.  It makes it easier when the time come to take your program from the breadboard to the train board, pinouts all are the same and it eliminates the problem of forgetting to change the loader over to a Nano board, speaking from experience here.

John also has a good point, I just received three Nano's from overseas and had to trash all three because they did not have a bootloader installed.  Thankfully they were cheap enough so putting them in the waste basket didn't sting much. Make sure if you do order from overseas that the Nano has the bootloader installed.  Have ordered several more with the bootloader installed and have not had any issues.

Good luck, hope this helps.

There's a way to load the bootloader, but for the price I bought them for, I didn't bother, seemed more trouble than it was worth, but it can be done.

Agree John, I played around for a bit trying to load a bootloader, no success and as you said as cheap as they are it is not worth spending much time troubleshooting,  just buy new ones.

I found the Nano's on Aliexpress.com for less than $3 shipped free with the bootloader, so that would be the way to go.

The first time I used a Nano, I found that I had to download and install the CH340 driver (for my system, the windows version). Then I had no problems. This could be part of your problem.

If changing the Arduino IDE to Nano board doesn't fix your problem, you might want to read this website
