could you please tell me how to identify the board revision number of an Arduino-Uno board?
Unfortunately there is no information available in the handbook or in the packing the board came with.
According to a picture I found on wikipedia  the board I have bought should belong to R3.
But refering to the Arduino website  I’m confused.
My board fits to the picture shown in  which is named “Arduino Uno SMD”, please find screenshot  enclosed too. But there is no revsion number shown directly beneath that picture.
Does this mean that it is an Atmega8?
I think by comparing schematics with my board step by step it will be somehow possible to find it out by myself. But I would like to know if there is an “official” resp. better way to get this information.
Thank you very much!
