BerryGPS-IMUv3 is ublox i2c not on the i2c pins for raspberry pi?

[johnsom]

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.
