It has a nice standard 0.1″x0.1″ prototyping grid with big pads
Comes with Stacking headers and plain header, choose whichever you want when soldering together
An IC pattern for adding DIP ICs up to 20 pins
Power rails down the middle and sides
A reset button and an extra general use button
Two 3mm general use LEDs, red and green, as well as 2 matching resistors
Real time clock (RTC) keeps the time going even when the Arduino is unplugged. The battery backup lasts for 2 years.
Included libraries and example code for both SD and RTC mean you can get going quickly.
Prototyping area for soldering connectors, circuitry or sensors.
Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run.
