What is the difference between the two Arduino Nanos?

Hello! I have a question.

If there is no difference, I wonder when it was updated. And I want to know where I can see it.

Thanks for reading.

They have the same Atmel Atmega328P CPU and same pinout.

You can program on one and copy it to the other and you'll be fine
