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, input with a pullup
or open drain. 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!

Please refer to the attached datasheet for more information!

We even have an Arduino library with example code written which will
set pin state, read and write from individual pins, and set the
pullups:
