Rpi expansion boards
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.
