I have read a whole bunch of old threads (that seem to veer off to talk about other chips) about these two chips.
I have read about Nick Gammon's techniques to reduce 328 (328P??) power consumption. As well as other articles on the topic.
What I still are murky on is the practical difference (not in HEX please LOL) between the chips..
I am planning on building a "bear bones" Uno to save power. The adafruit kit uses a 328 and I wish to use my 328P out of the Uno in the BB kit. I would stick with a stock Uno but it is a (relative) power hog over long term use.
I am still learning about the microcontroller world and programming in general... at a high level of understanding (ie: plain talk) what is the practical difference between these two chips?
Thank you very much in advance. I am trying to learn with out a prior computer or electronics background so sorry for the dumb questions...
