Audio Connection
The mangOH Red includes a 3.5 mm audio jack (CN500) for use with audio-enabled
CF3 modules. If supported by the CF3 module, the jack can be used to make a voice
call.
By default, the audio jack is connected to the onboard mangOH codec, and is
configured for use with a CTIA/AHJ-compatible headset. For details, see
page 29.
