I2C1

The primary CF3 module’s I2C1 signal connects to a hub that expands to the following sources, as 
shown in 

Figure 2-9

 on page 23:

•

GPIO/PWM expanders—Used internally on the mangOH Green for I/O functions such as driving 
LEDs, resetting board components, etc. For detailed information, refer to mangOH Green 
schematics available at 

mangoh.io

.

•

Accelerometer/Gyroscope—Accessible via API commands.

•

Battery gauge—Accessible via API commands.

•

Battery charger—Accessible via API commands.

•

IoT Connector 0 (CN1000)

•

IoT Connector 1 (CN1001)

•

IoT Connector 2 (CN1002)

•

Audio codec (U501)

All signal sources are enabled by default.

Note: The mangOH Green I2C interface operates in a single-master/multi-slave setup.
