Detailed Description

I2C Communication Parameters.

The BNO08x supports I2C frequencies up to 400kHz (Fast Mode).

I2C Addressing (per BNO08x datasheet):

• 0x4B when SA0 = HIGH (default)
• 0x4A when SA0 = LOW

Clock stretching: BNO08x can hold SCL low when data is not ready. scl_wait_us must be long enough to accommodate this (50ms recommended).
