The data lines of the camera interface are shared with the eMMC and microSD interfaces, so the camera
cannot be used simultaneously with these interfaces.
Audio
Audio functionality on the ConnectCore 6UL SBC Pro provides headphone, speaker, line-out, two line-
in, and microphone signals. A Maxim MAX98089 audio codec manages the audio interface. You can
configure the audio codec through the i.MX6UL I2C1 bus. For power management, the ConnectCore
6UL SBC Pro provides a switch for powering on and off the audio interface. The switch is controlled
with the I/O expander AUD_PWR/IO28 signal.
The headphone audio output of the audio codec is connected to a stereo audio jack located on the
front edge of the SBC. The table below shows the pinout of the audio jack connector:
