I'm the owner of new Razzberry board. Because in my Rpi installation I use many inputs , outputs (and also I2C) I would like to know which pins are really used by Razberry board?
Does it use only RS232 , GND and power pins. Does use I2C pins? If yes what address is used?

Only Rx, Tx, Vcc and Gnd.

Thank you.
