The Slice of Pi/O gives a Raspberry Pi an extra 16 buffered inputs or outputs. There's now quite a few people making boards with the MCP23017 driver chip on so there's lots of code examples about. The main features are:
  •  Buffered output/input (protects your PI from miswires, shorts, overload and general abuse)
  • Construction is very easy (suitable even for children with basic soldering skills)
  • Supports 3.3v and 5v operation (selectable by jumper)
  • Can be powered externally also (for when your project needs more than the Pi can provide, remove red jumper and wire to pad "EXT POWER")
  • SPI and I2C pins to standard 2.54mm pitch holes (fast and easy access)
  • GPIO pins to standard 2.54mm pitch holes (fast and easy access)
  • Daisy chainable to 128 ports! (for when you need more than just 16 I/O's)
  • 4 wire daisy chain connector (PWR/GND/SCL/SDA)
  • I2C address selectable (means you can run more than a single I2C board)
 Features:
  • Gold plated finish (Protection against oxidization means your device will outlast normal solder finish boards)
  • Comes as a complete "self solder" kit of parts
  • IC chip has decoupling capacitors to minimise noise
  • Upto 200ma at 5v can be drawn by the Pi
  • Upto 50ma at 3.3v can be drawn by the Pi
  • Pads for the MCP interupt pins
  • IC chip is socketed to allow for replacement if needed
  • Made in the UK
  • Dimensions: 35.5mm x 51.5mm x 18.9mm
