2.4 CF3 Module Signals

This section describes how CF3 module signals connect to the platform hardware components (described in
Hardware Component Connections on page
Important:
CF3 module signal availability depends on the module type—some modules may not implement certain
Extension signals from the CF3 specification.

2.4.1 ADC

The mangOH Yellow supports four CF3 module ADC (Analog to Digital converter) signal sources (ADC0-ADC3).
The ADC signals connect to the following sources, as shown in
• ADC0—IoT Connector 0 (CN1000, slot IOT0), pin 20
• ADC1—Battery Voltage Monitor (BAT_VOL_MONITOR)
• ADC2—Expansion connector (CN805), pin 9
• ADC3—IoT Connector 0 (CN1000, slot IOT0), pin 37 (Hardware modification required)

2.4.2 Audio (Analog and PCM)

The mangOH Yellow supports the CF3 module PCM (digital) audio signals. The signals connect via a Mux (analog
switch) to the following sources, as shown in
• 3.5 mm analog audio jack (Default configuration)
• IoT connector (Alternate configuration)
