    Today I received some chinese Nanos which actually feature the Atmega328PB instead of the P variant.
    I did not yet test any of the extra features yet but at least the device signature checks out.
    The boards are standard layout so the pins 3 and 6 are not useable on this board.

      Cool! Do you have a link to where you got them? I've had my eye on the atmega328pb for a while now.

        I got two different boards from the same seller:
        https://de.aliexpress.com/item/2pcs-Nano-3-0-controller-compatible-with-for-arduino-nano-Atmega328P-CH340-USB-driver-NO-with/32828478049.html?spm=a2g0s.9042311.0.0.SGrO1Y
        and
        https://de.aliexpress.com/item/Freeshipping-2pcs-lot-Nano-3-0-controller-compatible-for-arduino-nano-CH340-USB-driver-NO-CABLE/32818556647.html?spm=a2g0s.9042311.0.0.SGrO1Y

        They are not advertised to contain the PB and the pictures also show a P so I guess there is no guarantee...

          @fleinze these atmegas are backwards compatible. See https://forum.mysensors.org/topic/3969/upgrade-to-atmega328pb

            I guess the atmega328pb needs a board designed for it, though, if you are to get the benefits of the atmega328pb? If it's just behaving as a regular atmega328p, I'm not sure there's any point to it.
