Micro Dot Phat GPIO pins

Which GPIOs are used by the Micro Dot pHAT? Aside from SDA1 and SCL1 (and power), are any other pins used? I’d like to have a go at running two displays off one RPi. I suppose it’s not possible to modify the I2C addresses (and the datasheet seems to say there are only 4 addresses available anyway), so I’ll need to repurpose the EEPROM I2C bus for the second display. I’d just like to check there are no other pins which need connecting.

That’s it- just I2C, 5V and ground.
