Chinese Arduino Nanos with Atmega328PB

[fleinze]

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:

and

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.
