Arduino Pro Mini 328 - 5V/16MHz

This is Freaduino Pro Enhancement version, which 100% compatible with the original. We add two analog IO - A6, A7 , and Power Input side add auto recovery insurance, and be allowed USB and Power Supply at same time. 

Arduino Pro is blue! It's thin (0.8mm)! It's the Arduino Pro Mini! This is a 5V Arduino running the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software). Arduino 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 Arduino users start with the Duemilanove. 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.
