Hsic (Usb/Ethernet); I2C1 - mangOH Yellow Hardware Architecture Manual

2.4.5 HSIC (USB/Ethernet)

The mangOH Yellow supports the CF3 module's HSIC signals, which connect through a USB hub controller to the
following sources, as shown in
• IoT Connector 0 (CN601)—USB interface
• Wi-Fi+BT module (U300)—UART interface via USB to UART converter (U803)
• Expansion Connector (CN805)—SPI interface via USB/SPI bridge (U805)

2.4.6 I2C1

The mangOH Yellow supports CF3 module I2C1 signals, which connect to the following sources (directly or via an
I2C expander), as shown in
• Direct connection:
· Audio codec (U702) / 3.5 mm jack (CN701)
• Connection via expander:
· Gas/Pressure/Humidity/Temperature sensor (U507)
· Accelerometer/Gyroscope sensor (U520)
· Geomagnetic Sensor (U502)
· Light Sensor (U506)
· Real Time Clock (U701) / Buzzer (U406)
· NFC (U700)
· Battery charger (U1000)
· Battery gauge (U1002)
· IoT Connector 0 (CN601)
· Expansion connector (CN805)
· GPIO/PWM expander (U503)—Used internally on the mangOH Yellow for I/O functions such as driving
LEDs, resetting board components, etc. (see
· For detailed information, refer to mangOH Yellow schematics available at
resources-hardware.
• Connection via USB Hub controller (U703):
· Converts between CF3 HSIC signals and USB signals for the IoT card, Wi-Fi/BT module, and Expansion
connector.
