Help:
Differences between Arduino Nanos.
Hey guys
I have 3 Nanos, 2 MCU, and 1 AU and I can't find information about the differences...
Arduino store only sells one nano, but I know that MCU and AU are different packages.
Besides the different architecture and look, I can't find information or something that I could see the difference...

    I own a lot of arduinos and I think they're all AU. Maybe it's just a package difference ? With some cheap chinese model I need to use and old bootloader but otherwise it's nearly identifcal to my eyes

    @MrEliptik Yep, different packages but only chinese fabrucators have them, and most are AUs, but I have one MCU... was wondering , if so rare why different... It has a smaller MCU chip but a large 16 pins chip the AU doesn't have...

    @GyroGearloose I think the large chip you see on top is the same as the one on the other side of the AU model.
