    Yes, most ultrasonic sensors I have seen use two GPIO pins. You can use the pins on the Wolfson card to connect it. -- Ragnar

    They are normally used as the UART serial console, but that function is easy to disable.

    Raspberry Pi • View topic - Easily disable / enable serial console

    Then the two pins can be used as ordinary GPIO pins.

    From the schematic, I take it that the audio card uses the i2c pins (1.3 and 1.5) on the header - can I still connect to these pins for another i2c device?

    Yes, you can. I2C bus is designed for multiple devices.
