This is Freaduino Pro Enhancement version, which 100% compatible with the original. Elecfreaks added two analog IO (A6, A7) as well as Power Input side auto recovery protection to allow for USB and Power Supply at same time.
This is a 5V Arduino clone running the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino IDE). The Freaduino Pro does not come with connectors populated so that you can solder in any connector or wire with any orientation you need.
The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.
