I’m trying to test this IMU for a project I’m helping with, and I’ve gone through the [hookup guide and set everything up, but the examples aren’t working for some reason.
None of the Arduino examples from the library seem to be actually reading or outputting any of the information from the IMU, but it is on and connected like the hookup guide shows it should be. This is also a brand new board so none of the parts should be broken or anything.
With the first example listed (RotationVector) every time I run the code I get “BNO080 not detected at default I2C address. Check your jumpers and the hookup guide. Freezing…” in the serial monitor, despite everything being plugged in as shown in the guide.
Also, here’s the code for the first example in case no one wants to download/find it themselves

This example shows how to output the i/j/k/real parts of the rotation vector.
https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation
It takes about 1ms at 400kHz I2C to read a record from the sensor, but we are polling the sensor continually
between updates from the sensor. Use the interrupt pin on the BNO080 breakout to avoid polling.
Hardware Connections:
Attach the Qwiic Shield to your Arduino/Photon/ESP32 or other
Plug the sensor onto the shield
Serial.print it out at 9600 baud to serial monitor.

I also apologize if this is something super simple that I’m not getting or I’m not providing enough info. I’m still new to both coding and arduino/circuitry and I’m kinda stupid.](Qwiic VR IMU (BNO080) Hookup Guide - SparkFun Learn)
