it is your average arduino with extra pins for pwm/pwr/gnd for easy use of servos and the like.
The same is true for the analog pins for hooking up sensors, potentiometers and such.
It is very common, but with the new smd Arduinos I'd like to point out that using the 28 pin dip package on a socket allows for easy removal when making a standalone units for finished projects.
The cable is a little short and stiff.
As with all arduinos i criticize the lack for protective varnish on the bottom side of the pcb.
I've never had a short this way but its a source for failure all the same.
I usually use arduino megas for my projects, then downsize to standalone atmega328's or attiny85/84 when/if i get to a finished state.
i use this duemilanove clone as a programmer for my attinys.
Whatever your use, this is a decent microcontroller for a great price.
