Hello. I too am using the cheap variety of a Nano, no real problems. PC, Windows 10. However, now I cannot connect them. I developed a sketch using Mega2560, then tried to upload it to a Nano. I know the CH340 driver is installed, in fact, when I plug in the USB cable, it shows up as such in Device Manager. I've used the (old bootloader) option all along, successfully to this point. Now I can't get board info or do an upload. I've tried it on two different computers and three different Nanos.
I've tried updating/reinstalling the driver and the IDE. Any input is appreciated.
Thank you
Duke
