Adafruit Perma-Proto 40-Pin Raspberry Pi Half-Size PCB Kit

We put a PermaProto half-sized proto board in a blender with a Pi Cobbler and out emerged this very tasty confection - the 40-Pin PermaProto for Pi! It has the Cobbler baked right in. Simply solder the 2x20 box header in, and you get all the labeled breakouts with extra prototyping space, power rails, mounting holes and that gorgeous silk.
