Do you mean a breadboard? – Jivings Jun 21 '12 at 18:19

No, a board with level shifter for RS232 or SPI memory or a couple of I2C components something like http://elinux.org/BeagleBoard_Trainer board. – FarhadA Jun 21 '12 at 19:28

Adafruit has unidirectional and bidirectional Logic Level Converters among other goodies for the RasPi.
BitWizard B.V. also carries a range of I2C expansion boards and accessories,
Just came across this one on youtube available here for order(preorder)
RaspberryPI has also discussed the Gertboard, but I have yet to see pricing and availability details.

Thanks for the info, the Adafruit one is interesting but has no logic on it, it is just a prototype board.
I like the Gertboard, hope it will be available soon.
I may just make one instead of waiting, it can be faster. But thanks a lot for the list.

The Pi-Face looks like a great expansion board.
From the website:
- Allows you to control lights, motors etc and monitor digital inputs, switches, etc.
- Four switches and four LEDs on board for rapid prototyping
- Two onboard relays (10A) for easy control
- Buffered to protect the Raspberry Pi; high-current open collector outputs and schmit trigger buffer inputs
- Credit card size, stacks on top of Raspberry Pi
- Easy to connect with screw terminals
- Easy to program with C and Python libraries
From the looks of things this will allow you to take input from a myriad of sensors, and easily allow you to interface your Pi with external components like switches, relays, lights etc

Seeed Studio has Grove Base Hat for Raspberry Pi which provides GPIO connectors.
