I have a box of Nano knock-offs. I've accumulated them over a number of years from different suppliers. I'm currently experiencing a problem with a most recent batch of knock-off Nano's and thought how are they different than others I have bought.
I aware the CH340 USB to serial driver chip varies across the knock-offs. That issues has caused me grief getting the Arduino IDE's working with MS Windows drivers. Is there a sketch that scans the underlying hardware, like lshw from the command line of my Linux computer.
I've queried the internet for a solution before posting here. The results are how to read sensors. I'm looking looking for low level. If but nothing else it might tell me what microcontroller the boards have. Even with a magnifying glass the knock-off boards are hard to read.
