Adafruit Intros Prototyping Kit for Raspberry Pi
 

Electronics components maker Adafruit released one of the first accessories for Raspberry Pi, the $25 computing prodigy that's sweeping the world (of tech students, engineers, and electronics hobbyists). It launched the Prototyping Pi Plate, a PCB that can be installed on top of the Raspberry Pi, interfacing with its headers, providing a nice big prototyping area, half of which is "breadboard" style and the other half "perfboard" style. All the GPIO/I²C/SPI and power pins are broken out to 0.1", along the edges. The kit is augmented with custom tall header breakouts that create sufficiently large clearance with the Raspberry Pi PCB below. The prototyping plate sits above the metal connectors, out of the way and allows for plenty of workspace. Adafruit is yet to complete testing it on the Raspberry Pi, its sale page on the company website only allows people to "sign up" for one (gauging interest), Adafruit with get back to sign-ups by email when the kit is ready to sell.
