Hi there. I have successfully created my first sketch (for my model railway) and it works fine on a UNO R3. To install it on my model railway, I would like to have it on a Nano. I have purchased a pack of Elegoo Nano which have the CH341 USB/Serial chip. I have tried downloading and installing the the driver but I get the following window opening after the install completes:
The drive is successfully Pre-installed in advance!
Neither before nor after this do I see any COM port being available. I am a long term widows developer but I don't seem to be able to work around this.
I have an AZDelivery FTDI Serial Adapter FT232RL USB to TTL 3.3V 5.5V Module Mini Port for Arduino which I bought from Amazon. I saw a Youtube video which showed this being plugged into a Nano (but that one didn't have a USB connector on it) but this obviously doesn't fit on the Elegoo Nano.
I don't seem to be able to find a Nano that can be used with the FTDI adapter.
I am stuck. Can anyone give me some advice please?
Do you see any new device appear in Windows Device Manager after you connect a Nano to your computer?

The Pro Mini does not have a USB to TTL serial adapter chip on board so you need to connect a separate adapter like your FTDI module.
You can connect the FTDI module to your Nano and use that to upload and do serial communication with the computer if you like. I can provide instructions for this if necessary. However, I think we should make an effort to get the Nano working as it's intended to work first, since that's more convenient than having an FTDI module hanging off of it with a spaghetti of jumper wires.
If you connect your FTDI module alone (it doesn't need to be connected to the Nano or anything else) to your computer using the same USB cable as you were using with the Nano, do you see something show up in Windows Device Manager?
No, I don't get anything showing in Device Manager with the FTDI module. I have a Pro-mini coming tomorrow so we shall see. I can't think why the FTDI or the Nano don't show. The Uno comes up fine on COM3 so there doesn't appear to be anything basically wrong.
This makes me think that you have a damaged, defective, or charge-only USB cable. It's too much of a coincidence that the Nano and the FTDI module have the same issue. Try a different USB cable. Also, make sure the USB cable is fully plugged into the USB jack on the board and computer.
The only cable I had was to charge up a bluetooth speaker. I wonder if it is only wired for charging and not for data? I have ordered a new cable for tomorrow so we shall see. I think that you might be right on the money here.
