Incorrect I2C addresses in MB1854 (B-CAMS-IMX) schematics for IMU and ToF sensors

[Duc]

Hello,

There seems to be an issue with the I2C addresses listed in the MB1854 (B-CAMS-IMX) documentation and schematics (B01/B02).

The documents show:

• IMU: 0xD4 / 0xD5
• ToF: 0x52

However, these appear to be 8-bit addresses. The correct 7-bit I2C addresses should be:

• ToF (VL53L5CX): 0x29
• IMU (ISM330DLC): 0x6A / 0x6B

This can cause confusion when using standard I2C tools or drivers.

Could you please clarify or update the documentation to specify the address format (7-bit vs 8-bit)?

Thanks.

Indeed.

Unfortunately, this confusion is widespread - whatever form you use, you will find tools, drivers, documentation, etc which uses the other form!
