For I2C, you use the 14 pin connector; I too am concerned about the use of I2C and Ethernet (this was asked here):
What pins are free, if you use this board? Any at all? The spec sheet mentions that the interface uses SPI and i2c.
Industruino doesn't sell at breakout board; Winford sells one that seems like it will work; any other suggestions out there, especially if you have to use the Ethernet *and* I2C (if this is possible)?
