Hardware & Peripherals:
Low-level Peripherals and 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.
Current expansion boards
Heber Ltd has developed a USB expansion board containing a fully protected DIO, Real time clock (RTC), Battery backed SRAM, Unique serial number, A small amount of write once memory, High drain outputs, Stepper motor driver, Serial ports, Power off sensing, Security, Audio amplifier. The board is available with disk image now, and has C/C++ drivers.
Arduino Shield and Raspberry Pi
a little board with Arduino socket and Raspberry Pi socket you can power the boards with 12Volt or 5Volt http://www.progetti-hw-sw.it/raspberry.htm
Buffer Board How to make a Pi Buffer on Veroboard. Each of the 14 outputs can drive up to 500mA using a Darlington array.
Buzzberry Buzz-Board Interface
Buzzberry is an interface board enabling expansion using the Buzz-Board modular system designed primarily for educational use.
On 2nd January 2012, CJE/4D announced that they have a real-time clock (RTC) expansion board in the works: 
- 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.
GPIO isolated expansion/RTC
UT Electronics is developing a expansion board containing a fully isolated 16-I/O I2C GPIO expander and RTC, with extensive options for further expansion. C and Python libraries will be available at launch. The board will probably be sold as a kit, with SMT components already in place.
“À la mode” is an Arduino clone specifically designed to interface with the Raspberry Pi. You can of course connect a standard Arduino to a Pi USB port using a cord, but when you want a turnkey solution, how about an Arduino compatible “plate” (shield) that fits right on top of the Raspberry Pi with direct access to GPIO port? The Linux side handles all of the displays, human interfaces, and number crunching. The low power Arduino compatible “à la mode” board handles sensors, servos/motors, and provides a highly accurate real time clock.
PiBorg is a Robotics add on board which adds the ability to control motors - from small to large (including DC motors, Stepper motors, BLDC motors and Solenoids) from your Raspberry Pi. It supports feedback via Encoders and Potentiometers, allowing closed loop (servo) control of motors to set positions, velocities and accelerations and it is capable of monitoring drive current and voltages. The loop is PID based and as PiBorg is an Open Source project, you may change the code as you please. It has the ability to drive 10A motors and more, so you'll never be left underpowered with this board!
Pi232 RS232 board
Pi232 is an RS232 expansion board that plugs onto GPIO connector.
