Yes, it is ok for use with raspberry pi. Further her is some information with a link to some code for using it with raspberry pi.

The data sheet shows the SDA/SCL pins will work with 3.3V

The manual does say :
"

The table below shows the signals available on the feature header. Please note that I2C and SPI are functions utilised on the card so these cannot be changed for other functions.

"

I am not sure what that means but to me it sounds like it uses I2C so depending on how you are using it you may not be able to use I2C. The i2c pins are available on the cards other header on EX9 and EX11.

I'll be playing with my card later today I will post back if I2C works or if the card is using the bus.
