NOTE: 18-Dec-2021: The ATmega328 chip is now unobtainable at any distributors, due to the global semiconductor shortage. We have managed to obtain stock to be able to continue offering this item, however, the price was very high and this has necessitated a temporary price increase of $2.79 which is currently included in the price of this item.
