## Description

So many people had built the MCP23017 onto the slice of PI that we thought you might like a version on a PCB and with lots of extra functions. Special mention should go to Nathan for coming up with the original idea http://nathan.chantrell.net/20120602/raspberry-pi-io-expander-board/

- Easy to build kit
- Runs at 3v3 or 5v from the PI (red jumper)
- Runs off external power (remove red jumper and wire to pad "EXT POWER")
- 4 wire daisy chain connector (PWR/GND/SCL/SDA)
- Breakout for Interrupt A & B
- Daisy chain upto 8 for 128 I/O pins
- 2 x 8 way 0.1" pitch layout for instant "vero-ability" of all 16 I/O's
- 2 x 8 way 0.1" pitch common ground for ease of use.
- 0.1uf decoupling capacitor
