10.3 Logic Levels Diagram for AUX_VDDIO = 0
The figure below depicts a sample circuit with a third party magnetometer attached to the auxiliary I
2
C bus. It
shows logic levels and voltage connections for AUX_VDDIO = 0. Note: Actual configuration will depend on
the auxiliary sensors used.

I/O Levels and Connections for AUX_VDDIO = 0
Notes:
1. AUX_VDDIO determines the IO voltage levels of AUX_DA and AUX_CL
(0 = set output levels relative to VLOGIC)
2. All other MPU-6050 logic IOs are referenced to VLOGIC.
