GrovePI+, GPIO and I2C?



I'm trying to get the RFID reader pn532 to work with my Up2 board. I have connected the reader via the GrovePi board and need to add two GPIO pins to the controller. The Intel upm/mraa libraries require such as setup. See

Which pins / connection shall I use? Any suggestions?
I want to use python for my code.

Regards, O.
