On amazon i have bought several batches of Arduino Nanos. I recently bought a few more when i blew one when fiddling with it in a metal electrical box. (Printed a plastic box)
The new ones were giving me serial communication errors. I tried all of the fixes like driver updates, even tried to load via rst port. Nothing was working.
Then i looked at what i had bought closer. It was called a nano, even had nano stenciled on it. But the description was for a
“Nano V3.0 ATmega328P Nano Board CH340 5V 16M Micro Microcontroller”
So i switched the board type to ATmega328p
It worked.
A lot of the fixes said check board type. I thought i had, BUT a nano ATmega328p is not a Nano on the board type. It is a Atmega328.
Newbe error, but the atmega was greyed out and did not have nano in front of it. I thought it was a completly differnt board, since i bought a nano.
Again i am a newbe and thought all nanos were equal.
