Notes

Crystal requirement: The 32.768 kHz crystal (pins 26–27) is required for BNO085 operation. Use a crystal with 50 ppm tolerance and 22 pF capacitor loading.
Multi-function pins: Pins 6, 17, 19, and 20 have alternate functions depending on protocol mode (I²C, SPI, or UART).
Reserved pins: Pins marked RESV_NC must not be connected; they are reserved for future use.
