Arduino breakout shield from RepRap

Arduino Breakoutshield

The RepRap team introduced a simple breakout shield –

The Arduino Breakout Shield is a shield that plugs into an Arduino and provides all the Arduino pins as screw terminals. It is perfect for semi-permanent Arduino projects, or just general prototyping. It provides access to all the Arduino pins, as well as providing extra GND, 3.3v, 5v, and Supply voltage pins for convenience.

Those terminal blocks can be quite handy, a bit reminiscent of the Make controller’s setup. – Arduino Breakout
