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 I2C 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. CLKOUT is referenced to VDD.

3. All other MPU-6050 logic IOs are referenced to VLOGIC.
