On the Raspberry Pi, there are several connections which can be used for expansion:

  • The Rpi GPIO (General Purpose Input/Output) pins are exposed, that means that expansion boards are able to talk directly to the CPU.
  • The DSI connector will allow low-level interfacing with LCDs and other displays.
  • The CSI connector will allow camera modules to be added in future.

Current expansion boards

GertBoard

main page: Rpi Gertboard

This board is a buffer between your Rpi and the real world, use it to flash LEDs on and off, drive motors, run sensors and all that other fun stuff.[1]

Piface

Piface is simpler than the Rpi GertBoard (it's aimed at less experienced users), but also intended to connect to PCs and Android to be platform agnostic

CJE/4D RTC

On 2nd January 2012, CJE/4D announced that they have a real-time clock (RTC) expansion board in the works: [1]
