You got the wrong version.
The new I/O modules are version 2.2.
I updated the download page with the v2.2 eagle files.
They no longer use 328p. They use PCF8574 as I mentioned above.

Re: IO Expansion methods
I read about the PCF8574 chip on TI's site. Seems straight forward - less complex than using the 328P. But the question remains. How do I get more than just an on/off value from it?
BTW - I cannot seem to locate the 2.2 eagle files for IO on the download page.

Like
X = analogRead( i2cio-pin1)
Also didn't find newer Eagle files
And how do you send data to pin 1 vs pin3? I get the example above except for this.

No. For reading, just use the code I posted before:
