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.

Expansion boards by functions

Power Supply and Control

See also Comparison of power supply & management hardware.

BattBorg

BattBorg is a power converter for your Raspberry Pi which allows you to power the Raspberry Pi off batteries. It will work with most batteries/battery packs that are between 7-36V so it's great for 12V car batteries, 8xAA battery packs, and so on. Perfect for autonomous robot projects where using a USB charger is not an option.

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 the 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. It 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. It needs only one GPIO pin to operate, with the option of using a second GPIO pin to add the safe shutdown functionality.

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.[1]

Power Pi

The PowerPi is a flexible power supply and control board. It can power the Raspberry Pi from a 4-14VDC source or a single-cell Lithium-Ion battery. It has integrated battery charging, switch-over, and monitoring. The AVR power supervisor allows the Pi to be powered on and off autonomously and also provides RTC and watchdog functionality.

RemotePi Board

The RemotePi Board is an intelligent infrared remote controlled power switch add-on board for the Raspberry Pi2, B, B+, A+. It allows to switch power on and off using any button (configurable in learning mode) of an existing standard IR remote. Power is only cut after notifying the OS and giving it time to shut-down. It is mainly intended to remote control (using LIRC) and power off/on a mediacenter system. i.e OpenELEC, Raspbmc, XBian, RasPlex, Raspbian. The board is compatible to simple GPIO IR receiver and piggy backs onto the Raspberry Pi, no soldering required. For more information click here.

3V3 DC-DC Switched Mode Regulator

The Raspberry Pi uses a linear regulator to convert the input 5V to 3V3. This converter can be replaced with a more efficient switching mode to reduce the power needed. This can be useful when running the Pi on battery. More information and a ready-to-buy kit be found here

Raspberry Pi to Arduino Shields Connection Bridge

Raspberry Pi to Arduino Shields Connection Bridge allows you to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry. Using arduPi library, you will be able to make programs in Raspberry with the same code used in Arduino. To do so, Cooking Hacks Team have implemented conversion functions so that you can control in the same way as in Arduino all the I/O interfaces: i2C, SPI, UART, analog, digital, in Raspberry Pi.

Pi Tin

Not yet tested, comments welcome Project files for Eagle here: [6] Schematic and Board images: [7] [8] 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. [9] does very nice work and is hobbyist friendly at very reasonable prices.

The board also has a battery-powered RTC, and a variable (6-23V, nominally 12V) power port for a corded power supply. The X100 also has a reset switch, but the reset pin header (included with the X100) must be soldered onto the RPi itself.

Slice of Pi

Slice of Pi Ciseco have produced a convienient small break out board for the Raspberry PI. XBee style connector for XRF / XBee / RN-XV / XBT / RF-BEE etc. Has the SPI and I2C pins on one standard 8 way header and the Raspberry PI's 8 general purpose I/O pins on another for easy access. 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. Trevor Gowen's experimental LED BarGraph "board" has been "piggy-backed" onto one of these.
