    I recently purchased the BerryGPS-IMUv3. I have soldered it up and got it going on a Raspberry Pi 3.

    The UART/serial interfaces are working fine, PPS as I have wired it up looks ok too.

    I just don't see the ublox I2C chip on the bus, only the IMU.

    i2cdetect:

    0 1 2 3 4 5 6 7 8 9 a b c d e f
    00: -- -- -- -- -- -- -- -- -- -- -- -- --
    10: -- -- -- -- -- -- -- -- -- -- -- -- 1c -- -- --
    20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    60: -- -- -- -- -- -- -- -- -- -- 6a -- -- -- -- --
    70: -- -- -- -- -- -- -- 77

    Is the ublox i2c not wired up to the i2c bus on the board?

    Do I need to jumper in the ublox SCL and SDA into the upper pins to get access to that interface?

    I need both the UART and the I2C ports (with different messages) for a project.

    Thanks,

    Hi Johnsom
    We haven't connected the uBlox i2c pins to the i2c bus, but we have broken them out on the PCB.

    In the image below, I have highlight the uBlox i2c pins.    You would need to connect these to the pins highlighted in yellow, which connect directly to the Pi i2c pins.

     

    I hope this helps.

    Yes, this answers my question perfectly.  Thank you for the fast response.
