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

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,

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.
