RPi Expansion Boards

Introduction
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.

Meltwater's Switched Mode Power Supply Kit
This is a DC to DC switched mode power supply, another great add on board in Meltwater's range. It comes as a kit of parts, ready to be soldered together. This can supply a 5 volt output to a Raspberry Pi from an input of anywhere from 7 to 40 volts!

Testing has shown that the unit is around 80% efficient, where a comparable linear regulator (such as LM350T) was measured under 50% (based on a quick test).

Pi Supply Switch
The Pi Supply Switch is an "intelligent" power management device for your Raspberry Pi made by Pi Supply. This add on board has hard on/off switches as well as a soft shutdown switch, which initiates a safe shutdown using a simple Python script. This add on board allows you to cycle power on the Raspberry Pi without plugging and unplugging either your "wall-wart" power supply, or the micro-USB plug input to your Pi. It includes an LED status indicator, and 3 mounting holes for easy use in any project you have in mind. The Pi Supply Switch needs only one GPIO pin to operate, with the option of using a second GPIO pin to add the safe shutdown functionality.

Even better, it is an Open Source project, and comes with free stickers and a free noodle USB cable to connect to your Pi.

The Pi Supply was funded using the crowdfunding site, Kickstarter.

Pi Tin
Not yet tested, comments welcome Project files for Eagle here: Schematic and Board images: This board uses Microchip 16-pin GPIO expanders driven by SPI to provide up to 256 additional GPIO pins at a very low cost. Optionally, it can supply power for the board and the Raspberry PI.

The board can be made in a stackable manner allowing you to also place additional peripherals on the GPIO connector. It makes non-exclusive use of all four SPI pins as well as exclusive use of the CE0 Pin.

If you install (and power) the power supply components, the board will supply up to 1A at 5VDC. This is not enough to power all GPIO pins on a fully populated board, but in most applications should be sufficient to power the RPI and a reasonable number of GPIOs. An external power supply should be used for higher-power applications. This board should never be powered from the RPI as even one of the chips can draw more than the RPI can provide.

The power supply is quite flexible and will accept anything from 8-25VAC or 8-42VDC. It is based on a Recom module which provides a switching power supply in a form factor that is a drop-in replacement for 7805 series TO-220 linear regulators.

The 8 chips can be had for about $4@ or less and the power supply components total about $15. A fully populated board is about $49+PCB, $31+PCB for 64 GPIO pins.

You can have the PCB made at a variety of fabricators. does very nice work and is hobbyist friendly at very reasonable prices.

Comes as a kit of parts that needs to be soldered. Construction is very easy and suitable for children with basic soldering skills.

Slice of PI/O is a variation of the above produced by Ciseco based upon Nathan Chantrell's MCP23017/Slice of Pi "project". The MCP23017 may be powered from either the Pi's 3.3V/5.0V GPIO pins or, with care, an external psu. The use of a 5.0V power source means that the MCP23017's 16 (2 x 8) GPIO's can interface directly with 5V logic families etc. However, the Pi's own GPIO's, also available, will still need 3.3V - 5.0V level shifters.
