    Tested built in IR receiver and to a big surprise it can receive signal despite of being behind TV and looking towards the wall.

    Also tested with eMMC version of CM4 for flashing.
    To enter eMMC programming mode:

    • USB multiplexer selector switch to USB-C position
    • Press and hold User Button
    • Connect USB-C cable
    • Release User Button
    • Follow software procedure

    Still have to think how and where to fit connector or solder pads for Ambilight...
