BNO085 and ESP32-S3 unstable I2C address

[joseagraz]

I'm using the ESP32-S3 TFT Feather and the 9-DOF Orientation IMU Fusion Breakout (BNO085) with CircuitPython and a STEMMA QT cable. When connecting the devices, the default I2C address (0x4A) is not consistently recognized. An I2C scan often shows 0x09, no detection, or rarely 0x4A.

I tried adding a 2K pull-up resistor to SDA, but it didn't solve the issue reference

Is there a known solution for this problem? If not, what microcontroller would you recommend as a better fit for this sensor?
Any advice is greatly appreciated!

Do you need wifi? If so try an ESP32-S2, instead of S3. But I have not tested that recently. If wifi is not needed, try a chip that is not one of

Does not work well on i.MX RT10xx chips, ESP32, ESP32-S3.

as listed, such as a SAMD, RP2040, etc.
