My first posting to this in a while but hopefully I will be more active from now on as I have taken early retirement at the age of 53 
Here is my model of a ATmega168 Arduino which I had a bit of difficulty lighting in order to show of the bump mapped PCB tracks. I know the centre looks a bit bright but this was the best I found after fiddling about with numerous lighting options - settling for 5 area lights of differing sizes and strengths, and I hope the depth of field gives a hint of macro. Cycles rendered with 1024 samples.
