Note – Pro Mini requires the use of an external conversion board for programming. The Pro Mini comes in two versions – 5V/16MHz and 3.3V/8MHz, where 3V is slightly slower but uses less power and can be battery powered, which can be beneficial for miniature designs. For the same reason, it is not compatible with shields, but it still can be used with breadboards. The Arduino Pro Mini is similar to the Pro version, but due to size constraints, some pins have been removed from it.

There you will find a fantastic selection of sample designs, shields and modules – knowledge and creative ideas included. Before you move on to expand your understanding of the platform, take a look at our Arduino blog. You can find the product links to the boards in the article. We compared small and somewhat similar boards from different manufacturers. Our goal was to pick the best one, but it’s not that easy…

Today’s post was created to identify the best of the smallest boards available, taking into account their advantages. Size matters, they say – but that is not all. Design constraints sometimes require the use of really small boards.
