connecting I2C to P28 & 29 on the Prop Proto USB

Is it ok to connect other I2C components to the pins 28(SCL) and 29(SDA) Prop Proto USB board used for the EEPROM.

I have 3 other pins that are not used.I thought I will keep them fee future expansion.
The component I will be connecting is a I2C pressure sensor - MS4515DO.- Data sheet attached.
The sensor will be active almost all the time-.

Thank you.

    Yes, and it's a very common practice. The other components need to be quiet while the Prop boots up though (this shouldn't be a problem with slave I2C devices).
