The Adafruit Proto-Screw shield is one of those brilliantly simple ideas, a prototyping board with a screw terminal for each of the Arduino pins. The shield also has stackable headers so you can plug another shield on top and still have access to all the signals.
Supplied as a bare board, plus 1 x green and 1 x red LED, 1 x reset button, a set of stacking female headers and enough 3.5mm screw terminal blocks for 36 connections. All parts are through hole making this quite a straight forward board to assemble, see the Adafruit assembly guide.
4 x bonus terminals for your own signals
Dimensions 66 x 73 x 10mm (2.6 x 2.9 x 0.4in.)
Adafruit part no. 196
