Pro Mini 5V Arduino running the 16MHz bootloader. Pro Mini ATMEGA328P come without connectors. We recommend the first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off-board.
