This is a 5V iduino running the 16MHz bootloader. iduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time iduino users start with the UNO. It's a great board that will get you up and running quickly. The Iduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.
