Description

DESCRIPTION

Add another 16 pins to your microcontroller using a MCP23017 port expander. 
The MCP23017 uses two i2c pins (these can be shared with other i2c devices), 
and in exchange gives you 16 general purpose pins. You can set each of 16 
pins to be input, output, or input with a pullup. There's even the ability to get an 
interrupt via an external pin when any of the inputs change so you don't have to 
keep polling the chip.

Use this chip from 2.7-5.5V (good for any 3.3V or 5V setup), and you can
sink/source up to 20mA from any of the I/O pins so this will work for LEDs and 
such. Team it up with a high-power MOSFET if you need more juice. DIP package 
means it will plug into any breadboard or perfboard.

You can set the i2c address by tying the ADDR0-2 pins to power or ground, for up
to 8 unique addresses. That means 8 chips can share a single i2c bus - that's 
128 I/O pins!
