Teyleten Robot GY- BNO080 BNO085 AR VR IMU High Accuracy Nine-Axis 9DOF AHRS Sensor Module

Couple issues I ran into, been great after I got it working: - Wiring (for I²C mode): - PS0 and PS1 to ground → selects I²C - RST and BOOT to 3.3V - AD0 to 3.3V → address A (0x4B) - AD0 to GND → address B (0x4A) - Give it a moment to boot — needs ~100ms after power-up before init succeeds. I retry init in my loop instead of once at startup. - Over-polling causes problems: - Asking for 3 fused reports at 50Hz starved the chip's on-board fusion scheduler → output froze (quaternion stopped updating even though it looked "connected") - Reduced the load — rotation vector at 10Hz, raw accel/gyro at 50Hz — and it ran reliably - Skip the magnetometer if you don't need absolute heading — the mag-based rotation vector was flaky; Game Rotation Vector (gyro+accel only) was smooth and stable.

It didn't work. The ESP32 couldn't even detect the I2C device.

I used a Lonely Binary ESP32-S3 Wifi board to connect with this board the first time attempted it did not work. But when I placed both the ESP-32-S3 and the BNO085 on a breadboard and wired them with jumper wires it worked fine. I recommend using ChatGPT to get started it can show you how to wire the board and help writing the difficult code needed to deal with the 9 axis sensors and Magnetic compass. It is a very accurate chip.

After receiving these in the mail I was a little skeptical at first but after testing them out these chips really do the job well and their legiimate! Definitely ordering more of these!

Worked flawlessly with the BNO08X libaray. Tested on a Raspi 0 2W with python
